HIV vs. AIDS: What You Should Know About These Commonly Confused Terms

Updated Dec 3, 2024 | 11:43 AM IST

SummaryWorld AIDS Day, observed on December 1st, raises awareness about HIV/AIDS, promotes education, supports those affected, and advocates for global action to eliminate the pandemic, emphasizing early detection, treatment, and prevention.
World Aids Day

World Aids Day

The global challenge of HIV/AIDS remains one of the most pressing public health issues today. According to the latest data from UNAIDS, around 38.4 million people worldwide are living with HIV/AIDS, underlining the need for not only medical intervention but also comprehensive awareness, education, and social change. Despite the significant strides made in treatment and prevention, the confusion surrounding the relationship between HIV and AIDS still persists.

Young people have become influential advocates in the fight against HIV/AIDS. Research from UNICEF shows that youth-led initiatives can lower HIV transmission rates by as much as 45% in targeted communities. These young activists utilize digital platforms and peer-to-peer education to dispel myths, promote safe practices, and foster supportive environments for those affected by HIV/AIDS.

Dr Gowri Kulkarni, an expert in Internal Medicine, explains that while the terms HIV and AIDS are often used interchangeably, they are distinctly different. "HIV (Human Immunodeficiency Virus) is a virus that attacks the immune system, whereas AIDS (Acquired Immunodeficiency Syndrome) is a condition that occurs when HIV severely damages the immune system," she clarifies. To understand the implications of these differences, it's important to explore the fundamental distinctions between the two.

1. HIV is a Virus; AIDS is a Syndrome

HIV is the virus responsible for attacking the body’s immune system, specifically targeting CD4 cells, which are crucial for the body’s defense against infections. As HIV progresses, it destroys these cells, weakening the immune system over time. If left untreated, this continuous damage can lead to AIDS.

AIDS, on the other hand, is a syndrome, not a virus. Dr Kulkarni further elaborates that AIDS is a collection of symptoms and illnesses that emerge when the immune system is severely compromised due to prolonged HIV infection. It represents the most advanced stage of HIV, and is characterized by very low CD4 counts or the onset of opportunistic infections like tuberculosis, pneumonia, or certain cancers.

2. Not Everyone with HIV Develops AIDS

A key distinction to remember is that not everyone with HIV will progress to AIDS. Thanks to advancements in medicine, particularly antiretroviral therapy (ART), individuals living with HIV can manage the virus and maintain a healthy immune system for many years, or even decades, without ever developing AIDS. ART works by suppressing the virus to undetectable levels, effectively preventing the damage HIV would otherwise cause to the immune system.

Without treatment, however, HIV progresses through three stages:

- Acute HIV Infection: This stage occurs shortly after transmission and may include symptoms like fever, fatigue, and swollen lymph nodes.

- Chronic HIV Infection: Often asymptomatic or mildly symptomatic, the virus continues to damage the immune system but at a slower rate.

- AIDS: This is the final stage, marked by severe immune damage and the presence of infections that take advantage of the compromised immune defenses.

3. HIV is Transmissible; AIDS is Not

Another key distinction between HIV and AIDS is the way in which they are transmitted. HIV is highly contagious and can be transmitted through the exchange of bodily fluids such as blood, semen, vaginal fluids, and breast milk. It is primarily spread through unprotected sexual contact, sharing needles, or from mother to child during childbirth or breastfeeding.

AIDS, however, is not transmissible. It is not a disease that can be passed from one person to another. Rather, AIDS is the result of untreated, advanced HIV infection and is a direct consequence of the virus’s damage to the immune system.

4. Diagnosis Methods Differ

HIV and AIDS are diagnosed through different methods. HIV is diagnosed through blood tests or oral swabs that detect the presence of the virus or antibodies produced by the immune system in response to the virus. Early detection of HIV is crucial, as it allows for timely intervention and treatment, which can prevent the virus from progressing to AIDS.

AIDS, on the other hand, is diagnosed using more specific criteria. Dr Kulkarni notes that the diagnosis of AIDS is made when the individual’s CD4 cell count falls below 200 cells/mm³, or when opportunistic infections or certain cancers (such as Kaposi's sarcoma or lymphoma) are detected. Diagnosing AIDS involves a more thorough assessment of the individual’s immune function and overall health, as opposed to just the detection of HIV.

5. Treatment Goals Are Different

The treatment goals for HIV and AIDS differ significantly, although both involve antiretroviral therapy (ART). For HIV, the primary treatment goal is to suppress the virus to undetectable levels, thus maintaining a strong immune system and preventing further transmission of the virus. People living with HIV can often live long, healthy lives if they adhere to ART.

For individuals diagnosed with AIDS, the treatment plan becomes more complex. While ART remains an essential part of managing the virus, treatment for AIDS also focuses on addressing the opportunistic infections and secondary health complications associated with severe immune suppression. The goal of treatment for AIDS is not only to manage the HIV virus but also to improve the quality of life and extend survival by treating these secondary health issues.

Role of Community Engagement in Combatting HIV/AIDS

While the medical community has made great strides in managing HIV, the battle to curb its transmission is also a social and cultural issue. Dr Daman Ahuja, a public health expert, highlights that HIV/AIDS awareness and education are vital to reducing transmission rates and supporting those affected by the virus. "Young people, especially, have become key advocates in the fight against HIV/AIDS," says Dr Ahuja. "Research from UNICEF shows that youth-led initiatives can lower HIV transmission rates by as much as 45% in targeted communities."

Additionally, grassroots activism plays a significant role in raising awareness and addressing stigma. As the World Health Organization reports, community-based interventions have been proven to increase HIV testing rates and improve treatment adherence, which are crucial in the fight against the pandemic.

The ultimate goal of organizations like UNAIDS is to eliminate the HIV/AIDS pandemic by 2030. Achieving this requires global collaboration, from medical treatment advancements to public health strategies, education, and advocacy. Dr Kulkarni’s insight underscores the importance of early detection, treatment adherence, and community support in the fight against HIV/AIDS.

Dr Gowri Kulkarni is Head of Medical Operations at MediBuddy and Dr Daman Ahuja, a public health expert and has been associated with Red Ribbon Express Project of NACO between 2007-12.

Not All Vitamins Work The Same For Women: What and When To Take|Women's Day Special

Updated Mar 3, 2026 | 06:20 PM IST

SummaryMultivitamins are essentially dietary supplements often used to bridge nutritional gaps in the diet, treat deficiencies caused by poor nutrition or illness and support overall health. But which vitamins do women need and when should you be taking them?
Not All Vitamins Work The Same For Women: What and When To Take| Women's Day Special

Multivitamins are essentially dietary supplements containing a combination of various vitamins and minerals, often used to bridge nutritional gaps in the diet, treat deficiencies caused by poor nutrition or illness and support overall health.

Designed to provide a broad range of nutrients in one daily dose, they are available in tablets, capsules, gummies or liquids and are widely recommended to adults of all ages and genders.

But which vitamins do women need and when should you be taking them?

Dr Yashica Gudesar, Director & Unit Head of Obstetrics & Gynecology, Max Super Speciality Hospital, Dwarka exclusively tells Healthandme: "A woman’s nutritional needs change at different stages of life, from adolescence to reproductive years, pregnancy, and menopause. While food should always be the primary source of nutrients, certain vitamins may be required as women age or depending on lifestyle, diet, and health conditions."

"There’s honestly no universal vitamin checklist that works for every woman. The needs change with age, lifestyle, stress, whether one is planning a pregnancy, and of course, what the blood reports actually show," Bhakti Samant, Chief Dietician, Kokilaben Dhirubhai Ambani Hospital further told this publication.

Here are the supplements you need to stock your medicine cabinet with:

1. Vitamin D

Vitamin D is a fat-soluble nutrient essential for strong bones, immune function, and calcium absorption, often synthesized when skin is exposed to sunlight or obtained via food and supplements.

Symptoms of Vitamin D deficiency include bone pain, muscle weakness, and depression. Deficiencies are common due to low sun exposure or poor diet, leading to rickets in children and osteomalacia or osteoporosis in adults.

However, this can be avoided by consuming a combination of calcium and Vitamin D supplements. Dr Ginni Kalra, Head Dietician, Aakash Healthcare explained to Healthandme: "One of the frequently deficient nutrients in women is vitamin D. It is very important in calcium absorption, bone density, immune homeostasis and mood balance. In most adult women, the amount needed is 600-800 IU (15-20 mcg) per day although deficient women can take 1000-2000 IU per day under the supervision.

"Calcium is necessary in bone density especially in women post-menopause who experience rapid bone loss owing to the diminishing estrogen. Adult women should take 1,000 mg per day that rises to 1200 mg past 50 years. Calcium supplements are most ideal in separated doses of 500-600 mg each time and preferably following meals. When combined with vitamin D, absorption will enhance much better."

"Calcium becomes especially important after the age of 30, and even more after menopause. It can be taken after meals, often divided into two doses for better absorption," Dr Gudesar added.

Moreover, Samant advised: "Vitamin D is best taken with a meal that has some fat. Calcium (around 1000–1200 mg daily) is better split into two doses and should not be taken with iron."

2. Iron

A vital mineral, iron plays a very crucial role in human functioning by helping create hemoglobin to transport oxygen throughout the body, essential for energy and muscle function. Low iron levels can result in decreased oxygen transport and leading to symptoms like extreme fatigue, weakness, pale skin, cold hands/feet and shortness of breath.

While an iron deficiency is usually caused by poor diet, blood loss due to menstrual periods, ulcers, cancer, or regular use of pain relievers like aspirin or malabsorption issues, it can be remedied through supplements.

Dr Kalra explains: "Iron is also essential especially in menstruating women because they lose blood monthly. It may result in an iron deficiency which causes fatigue, loss of hair, brittle nails, and poor concentration. The acceptable amount of iron that is recommended to be taken by women aged 19 to 50 is approximately 18 mg, but this reduces to 8 mg after menopause.

"Iron supplements are better absorbed on an empty stomach or when taken with vitamin C and not when they are taken with calcium, tea or coffee as they have been found to interfere with absorption. The intake in the morning is usually desirable, but in case of gastrointestinal discomfort, it should be avoided."

3. Vitamin C

Vitamin C is essential for the body because it serves as a powerful antioxidant, supports the immune system, and is crucial for the synthesis of collagen, which is vital for wound healing and the maintenance of healthy skin, bones, and blood vessels.

It also enhances the absorption of iron from plant-based foods and protects cells from damage caused by free radicals, potentially reducing the risk of chronic diseases like cancer and heart conditions.

While, foods such as oranges, lemons, red and green peppers, kiwifruit, broccoli, strawberries, and Brussels sprouts can provide help maintain Vitamin C levels, supplements can help boost absorption and maximize benefits.

Dr Kalra notes: "Vitamin C helps to maintain the immunity, collagen synthesis, and iron uptake. It should be taken in 75 mg daily by adult women. It is soluble in water and can be consumed together with breakfast."

Additionally, she also recommends intaking: "Vitamin E and vitamin A also help the skin, vision, and antioxidant defense, but overconsumption is not advisable because it may be toxic."

4. Omega 3

Omega-3 fatty acids are polyunsaturated fats known for their crucial role in brain function and overall mental health. Fish oil is particularly rich in EPA and DHA, which are vital components of cell membranes and have strong anti-inflammatory effects in the body.

These omega-3s play a critical role in human development, and they are primarily found in fatty fish and fish oil. Some popular sources of Omega-3 include:

  • Salmon
  • Cod Liver Oil
  • Algae Oil
  • Oysters
  • Nuts and seeds, such as flaxseeds, chia seeds, and walnuts
  • Plant oils, such as flaxseed oil, soybean oil, and canola oil
  • Fortified foods, such as eggs, yogurt, juices, milk, etc.

But as many people do not consume enough fish, supplementation is often recommended to ensure adequate intake of these essential fatty acids.

Dr Kalra suggests: "Though not vitamins, omega-3 fatty acids are worth mentioning because of the cardiovascular, hormonal, and anti-inflammatory effects. About 250–500 mg of combined EPA and DHA a day may be helpful and is most often administered after meals."

5. Vitamin B12

Vitamin B12 (cobalamin) is a crucial water-soluble vitamin necessary for brain health, nerve tissue, red blood cell formation, and DNA synthesis. It helps the body produce red blood cells, supports your nervous system and essential for making DNA, which is the genetic material inside all your cells.

Symptoms of a Vitamin B12 deficiency often appear slowly. You may not notice them at first, or may blame them on stress, lack of sleep or a busy schedule. However, if the deficiency continues for long, it could lead to serious health problems.

Dr Gudesar recommends: "Vitamin B12 supports nerve health and energy levels. Vegetarian women are more prone to deficiency. It is typically taken in the morning."

"Vitamin B12 is needed to promote nerve well-being, red blood cell building, and energy conversion. The chances of deficiency are increased in vegetarian women because B12 is mostly found in foods of animal origin. The suggested daily dose is 2.4 mcg, but the dosage can be raised in deficiency. It is preferable in the morning as it could increase alertness," Dr Kalra explained.

However, Dr Kalra also advises: "There should be individualization of supplement timing and dosage. Decisions should be based on routine blood tests, dietary assessment, age, lifestyle, and existing medical conditions.

"Excessive supplementation is detrimental, in particular, fat-soluble vitamins. The only safe and effective approach is nutritional adequacy by means of whole foods, and supplements are the supportive therapy only in cases where deficiencies are observed."

The digital revolution has transformed childhood. From online classes to gaming and entertainment, headphones and earphones have become constant companions for children. While technology has brought convenience and learning opportunities, it has also introduced a silent threat, damage to children’s hearing.

In my clinical practice as an ENT surgeon, I am witnessing an alarming increase in young patients presenting with symptoms such as ear discomfort, ringing in the ears (tinnitus), and reduced hearing ability. These issues, once uncommon in children, are now becoming increasingly frequent due to excessive and unsafe use of personal audio devices.

Understanding the Risk

The primary concern is noise-induced hearing loss, caused by prolonged exposure to loud sounds. When children use earphones at high volumes for extended periods, delicate hair cells in the inner ear get damaged. Unfortunately, this damage is permanent and cannot be reversed.

What makes the situation more concerning is that children often do not recognize the early warning signs. By the time symptoms become noticeable, significant damage may have already occurred.

The 60/60 Rule: A Simple Preventive Measure

One of the most effective ways to protect hearing is by following the 60/60 rule:

• Listen at no more than 60% of the maximum volume

• Limit usage to 60 minutes at a time, followed by a break

This simple guideline can significantly reduce the risk of hearing damage and should be strictly followed by children and adolescents.

Warning Signs Parents Must Watch For

Parents play a crucial role in early detection. Some common warning signs include:

• Frequently increasing the volume of devices

Complaints of ringing, buzzing, or ear pain

• Difficulty in hearing conversations

• Speaking unusually loudly

If any of these symptoms are noticed, it is important to consult an ENT specialist promptly.

Promoting Safe Listening Habits

Preventing hearing loss requires consistent effort and awareness. Here are some practical tips:

1. Limit Earphone Use: Encourage children to use speakers whenever possible instead of earphones.

2. Choose Safer Devices: Over-the-ear headphones are generally safer than in-ear earbuds as they reduce direct sound impact.

3. Ensure Quiet Environments: Avoid using headphones in noisy surroundings, as children tend to increase volume to compensate.

4. Take Regular Breaks: Continuous listening should be avoided. Short breaks help the ears recover.

5. Avoid Night-time Use: Using headphones before sleep can harm both hearing and sleep quality.

A Shared Responsibility

Protecting children’s hearing is not solely the responsibility of doctors. Parents, teachers, and schools must work together to create awareness about safe listening practices. Educational institutions can include digital health education, while parents should monitor and guide their children’s device usage.

Routine hearing check-ups should also be encouraged, especially for children who frequently use headphones for study or entertainment.

The digital age is here to stay, and technology will continue to play a central role in children’s lives. However, safeguarding their health must remain a priority. Hearing is a precious sense that, once lost, cannot be restored.

By adopting simple precautions, spreading awareness, and encouraging responsible use of technology, we can ensure that our children enjoy the benefits of the digital world, without compromising their hearing health.

Ozempic Can Raise Your Risk Of Osteoporosis, New Study Reveals

Updated Mar 4, 2026 | 02:00 AM IST

SummaryOzempic, Wegovy, Zepbound, Mounjaro are few of the world’s most famous weight loss medications right now. While people are taking this to lose weight, there are many side-effects that one should consider. A new study has revealed that it could be a risk to one’s bone health as well.

Weight loss injections like Ozempic and Wegovy have taken over the world because of the transformative effect they have on people’s weight. However, these medications also have unwanted side-effects and a new study revealed that these medications also put your bone health at risk.

Although the weight loss injections are being hailed as revolutionary for its benefits like better heart health, lower risk of type-2 diabetes and even cognitive health, there is a significant trade off. Conducted by Dr. John Horneff, an associate professor of orthopedic surgery at the University of Pennsylvania, the study revealed nearly 30 percent increase in the risk of osteoporosis.

While the medication was originally made for people with type-2 diabetes, it quickly rose to fame because of its weight loss side-effect. However, soon people started experiencing side effects like excessive lose skin, loss of fat from essential body parts like pads of feet, vulva, etc. However, studies have found long-term effects of these medications as well, things that are not so apparent.

How Does Ozempic Affect Bone Density?

The numbers show that about 4 percent of GLP-1 users developed the condition, compared to roughly 3% of those not taking the meds. While that sounds small, it represents a 30 percent increase in risk.

Even more concerning was the rise in osteomalacia (a softening of the bones), which occurred twice as often in those taking the medication. Researchers are still trying to figure out exactly why this happens, but they have a few strong theories:

Nutritional Gaps

Since these drugs suppress appetite, patients often eat significantly less. If they aren't careful, they may miss out on bone-building essentials like calcium and vitamin D.

The "Astronaut" Effect

When you lose weight very quickly, your skeleton suddenly has a much lighter load to carry. Similar to how astronauts lose bone density in zero gravity because their bones aren't being "challenged," rapid weight loss may tell the body it doesn't need as much bone mass to support its new, lighter frame.

Hormonal Changes

Women in perimenopause or menopause are already at risk because their estrogen levels (which protect bones) are dropping. Rapid weight loss can add fuel to that fire. The study also flagged a 12 percent increase in the risk of gout, a painful type of inflammatory arthritis. This is likely because quick weight loss can cause a temporary spike in uric acid levels, which leads to painful joint swelling.

Can You Decrease Your Risk of Osteoporosis On GLP-1?

Experts explain that it is possible to lower the effects of weight loss medications on your bones. The goal of this research isn't to scare people away from these life-changing medications, but to help them use them more safely. Experts suggest focusing on a few key areas to keep your frame strong while the pounds come off:

  • Prioritize Nutrition: Focus on high-protein foods and ensure you’re getting enough Vitamin D and calcium.
  • Start Lifting: Weight-bearing exercises and strength training are vital. Putting "good" stress on your bones signals your body to keep them dense and strong.
  • Talk to Your Doctor: If you are an older adult or a woman in menopause, ask your provider about monitoring your bone density while on the medication.
