A woman's health is intricately linked to her menstrual cycle, which is an important sign of her overall well-being. Throughout puberty and menopause, hormonal changes affect not only fertility but also mood, energy, and long-term health. A normal cycle usually indicates balance, whereas abnormalities may suggest problems such as PCOS, endometriosis, or thyroid disease.

Our bodies do not always work in a perfect clockwork operation and unexpected vaginal bleeding can often confused us. Is it a mere spotting? A normal period? A symptom of something more concerning? Differences between spotting, menstrual bleeding, and intermenstrual bleeding should be understood is crucial for maintaining reproduction health.

Here is a short guide to help you differentiate while you are confused.

Spotting

Spotting is vaginal bleeding that doesn't happen as part of your regular menstrual period. It commonly manifests as fine droplets or smears of blood on clothing or toilet tissue. The intensity of the blood ranges from deep red (recent blood) to pink (having cervical mucus mixed in it) or brown (older, oxidized blood). Spotting is not very much and can't be seen in a way that needs either a tampon or a pad to absorb.

Common Causes of Spotting

Spotting is caused by numerous factors, and in the majority of instances, it is nothing to worry about. Some frequent causes are:

Hormonal Birth Control Transitions: New birth control technique, for instance, birth control pills, IUDs containing hormones, or implants, results in temporary spotting as the body adapts.

Ovulation Bleeding: A few individuals get spotting light around the time of ovulation as a result of hormonal changes. It normally happens in the mid-cycle and could be followed by slight cramping.

Cervical Ectropion: A harmless condition when cells from the inside of the cervical canal migrate to the outer cervix, causing the outer cervix to become more sensitive and prone to faint bleeding on coitus or physical activity.

Early Pregnancy (Implantation Bleeding): 15–25% of pregnant women experience light spotting around 10–14 days post-conception, which is confused with an early period.

When to See a Doctor

Spotting is usually harmless, but it's best to consult a doctor if:

• It continues after a few months of initiating new birth control
• Is accompanied by pelvic pain or abnormal discharge
• Occurs after frequent intercourse
• Occurs during pregnancy and is not verified as implantation bleeding

Menstrual Bleeding

There is a time, also known as a period or menstruation, when the uterine lining sheds due to changing hormone levels. It would last for approximately 2-7 days and is heavier initially. The hue and texture of period blood shift during the menstrual cycle:

Red: New active bleeding at the start of a period

Brown or dark red: Older, slower blood in leaving the uterus

Clots: It's normal to have small clots, but bigger clots may be a sign of heavy menstrual bleeding (HMB)

Why You Have a Period Essentially?

Menstruation is a part of the reproductive cycle, and it happens around every 21–35 days. When there's no pregnancy after ovulation, hormone levels fall, causing the uterine lining to be shed.

Signs Your Period May Be Abnormal

Though periods differ in different people, there are some signs that point towards probable underlying conditions:

• Prolonged bleeding (longer than 7 days)
• Heavy flow necessitating pad/tampon changes every 1–2 hours
• Severe cramps that disrupt daily life
• Irregular periods or absent periods

If you have any of these, conditions such as polycystic ovary syndrome (PCOS), endometriosis, or thyroid disease may be involved, and a medical visit is in order.

Intermenstrual Bleeding

Unlike spotting, intermenstrual bleeding is heavier and unexpected between regular periods. It may be from bright red to dark brown and can contain blood clots.

Possible Causes of Bleeding Between Periods

Sexually Transmitted Infections (STIs): Chlamydia and gonorrhea can lead to inflammation and abnormal bleeding.

Pelvic Inflammatory Disease (PID): A bacterial infection of the reproductive organs and can lead to abnormal bleeding.

Uterine Fibroids or Polyps: Benign growths in the uterus that may cause unexpected bleeding.

Endometrial Hyperplasia or Cancer: In some instances, abnormal bleeding may be a sign of abnormal cell growth in the lining of the uterus.

When to See a Doctor

See a doctor if intermenstrual bleeding is:

• Frequent or persistent
• Associated with pelvic pain or discomfort
• Associated with abnormal discharge, fever or painful sex

Recognizing your body's rhythms can assist you in identifying normal versus abnormal bleeding. Monitoring your menstrual cycle through an app or calendar may flag changes that should be checked with a doctor. If you have any questions regarding abnormal bleeding, visiting your health care provider is the way to go.

August 18 marks World Breast Cancer Research Day, a day that reminds us that every major breakthrough in cancer care has its roots in research. The medicines that are prescribed, the diagnostic technologies that we use, the targeted therapies that we offer and our growing understanding of why cancers develop and spread, are all outcomes of regular scientific research.

India carries one of the world's largest cancer burdens. According to IARC's GLOBOCAN 2022 estimates, India recorded approximately 1.41 million new cancer cases and more than 916,000 cancer deaths in 2022. Breast cancer alone was the leading cancer among Indian women and also the leading cancer overall.

India as a country, has a large and diverse patient population, significant clinical expertise, strong medical institutions and a pharmaceutical industry with enormous manufacturing capabilities. But there is a crucial gap between manufacturing what the world has already discovered and researching newer medical opportunities.

A significant proportion of cutting-edge cancer research continues to emerge from countries with substantially larger and more established research ecosystems. When scientific discoveries, new molecules, diagnostic technologies or treatment approaches are developed elsewhere, Indian patients benefit from them at a later stage.

We Need To Move Beyond A Few Centres Of Excellence

We have limited institutes that have made important contributions to cancer care and research. But considering India's population and cancer burden, the scale of research infrastructure needs to expand substantially. We need more dedicated cancer-research institutes, stronger university hospital industry collaborations, modern laboratories, biobanks, genomic databases, data-science capabilities and trained physician-scientists.

Cancer is not just one disease. It comprises of multiple biological subtypes, and the way a tumour behaves can vary significantly between individuals and populations. Therefore, India needs research that focusses specifically towards Indian patients.

Clinical Trials Can Be Part Of The Solution

India has a formal Clinical Trials Registry, and the registry currently records more than 100,000 trials across areas of medicine.

For eligible patients, participation in an appropriate clinical trial may provide access to an investigational therapy or treatment strategy that is not yet routinely available. Clinical trials generate evidence that can improve future treatment for thousands or millions of patients.

Research Needs To Become A Policy Priority

We need to create an ecosystem that moves from discovery to translation to patient care. That means incentivizing research institutions and researchers, supporting young physician-scientists, strengthening public-private partnerships and making it easier for promising discoveries to move from laboratories into clinical development.

We need to have an ecosystem, where healthcare research, particularly research addressing diseases with an enormous Indian burden should receive a much greater and more targeted share of national research investment. A large, diverse population can generate valuable real-world evidence. Large patient cohorts can help researchers understand disease patterns. Indian genetic and molecular data can help answer questions that may not be adequately addressed through studies conducted in other countries.

From Manufacturing Medicines To Discovering The Next Generation Of Treatments

India has already demonstrated that it can serve the world as a pharmaceutical manufacturing powerhouse. We should look at also becoming the research hub for the world by combining our pharmaceutical manufacturing strength, clinical expertise, technology capabilities and patient population.

The opportunity is already in front of us.

What we need now is the policy ambition to implement it.

If you believe having a healthy body mass index (BMI) means you have a low risk of heart disease, you may be wrong. A new study suggests that abdominal fat may predict cardiovascular disease risk better than BMI alone.

The study, published in the Journal of the American College of Cardiology (JACC), found that failing to account for waist circumference (WC) or waist-to-hip ratio (WHR) may lead to misclassification of cardiovascular disease risk.

“Indeed, it appears that WC and WHR reclassify risk defined by traditional BMI thresholds,” said Michael J. Blaha, director of clinical research at the Johns Hopkins Ciccarone Center for the Prevention of Cardiovascular Disease.

“We saw individuals with clinically determined normal weight who had elevated central adiposity and high WHR, associating them with higher risk across most outcomes,” Blaha added.

Why BMI Alone May Not Predict Heart Risk

BMI is calculated by dividing weight in kilograms by height in meters squared and is commonly used to diagnose overweight and obesity. However, BMI does not show where body fat is distributed.

• Visceral fat surrounds the internal organs in the abdominal area and is associated with chronic conditions such as heart disease and diabetes.
• Subcutaneous fat is located directly under the skin and is not as strongly associated with these conditions.

What Did the Study Find?

The study examined whether adding WC and WHR to BMI could better predict future cardiovascular risk. Researchers looked at more than 260,000 people over an average of 20 years. They found that central adiposity could identify cardiovascular risk that BMI alone may miss.

Among people classified as having normal weight by BMI:

• 5% had high waist circumference
• 18% had high waist-to-hip ratio

• 39% had high waist circumference
• 40% had high waist-to-hip ratio

• 9% had low waist circumference
• 45% had low waist-to-hip ratio

People with normal weight or overweight who had clinically defined high WC or WHR had a 15%–50% greater risk for most heart problems.

People with obesity and low WC did not have a significantly different risk of outcomes compared with those who had normal weight and low WC, except for all-cause mortality, for which their risk was significantly lower.

“Our findings emphasize the critical role of identifying elevated central adiposity, even in individuals with a normal BMI or with a BMI in the overweight range. Relying solely on BMI may result in misclassification of cardiovascular risk across a wide range of cardiovascular outcomes,” said Zeina A. Dardari, lead author of the study.

“We encourage clinicians to consider central adiposity distribution across the entire BMI spectrum when evaluating cardiovascular risk in primary prevention settings,” she added.

What Were the Study's Limitations?

The researchers did not have information on several factors that can influence cardiovascular disease risk, including:

• Physical activity
• Diet
• Genetic risk for obesity

The study also included only one assessment of waist circumference and waist-to-hip ratio. This limited the researchers' ability to understand how changes in abdominal fat accumulation over time may influence cardiovascular disease risk.

Organ donation is one of the most profound ways in which we can give the gift of life to another person. World Organ Donation Day, observed every year on August 13, is an opportunity to raise awareness about organ donation, address common myths and encourage more people to consider pledging their organs. India has a large number of patients waiting for organ transplants, including transplants of the liver, kidney, heart, pancreas, intestine and other organs and tissues.

Despite the significant need, organ donation rates remain low, with lack of awareness and several misconceptions continuing to be major barriers. One organ donor can potentially save multiple lives. However, for this to happen, it is important that people understand the process and make an informed decision about organ donation during their lifetime.

Busting Common Myths About Organ Donation

1. “My religion does not permit me to donate my organs.”

2. “Organs can only be donated after the heart stops beating.”

For most organs, donation after brain death is possible when the brain has permanently stopped functioning, but the heart is still beating, which generally occurs in an intensive care setting. Corneas can also be donated after death within a limited time period. This is why pledging your organs during your lifetime and discussing your decision with your family is important.

3. “Organ donation will disfigure or mutilate the body.”

Organ retrieval is performed by trained medical specialists in an operating theatre. The surgical incision is carefully closed after the procedure, and the body is not mutilated.

4. “I can buy a kidney or liver for my family member.”

5. “If I donate a kidney, I will become weak or handicapped.”

A healthy person who is found suitable for living kidney donation through the required medical evaluation can generally continue their normal life after donation. The remaining kidney is capable of maintaining normal kidney function.

6. “A kidney donor has to take lifelong medicines.”

Kidney donation does not mean that a healthy donor has to take lifelong medication simply because they have donated a kidney. Some pain medication may be required during the initial recovery period, while the remaining healthy kidney continues to perform its function.

7. “I will have severe dietary restrictions after donating a kidney.”

According to the source material, kidney donors do not generally need specific dietary restrictions solely because they have donated a kidney, as the remaining kidney continues to maintain normal kidney function.

8. “I will not be able to have children after donating a kidney.”

Both men and women who donate a kidney can have children. For women, the source recommends waiting one year after donation before becoming pregnant to allow the body to recover completely.

9. “I am over 60, so I am too old to donate.”

Age alone does not determine whether someone can donate. The health of the donor and the condition of the organs are important considerations, and suitability is determined through medical evaluation.

What Can We Do To Encourage Organ Donation?

• Consider pledging your organs during your lifetime and communicate your decision clearly to your family.

• Talk to your family, friends and colleagues about organ donation and help dispel common myths.

• Encourage community organisations to participate in creating awareness around organ donation.

• Do not assume that you are medically unfit to donate. A team of medical experts evaluates the donor and determines suitability.

• Organ donation is a completely voluntary decision. No individual should be pressured into donating an organ.

• Patients waiting for an organ transplant should approach a licensed transplant hospital and complete the necessary registration formalities, including through the NOTTO system.

Organ donation is ultimately about giving someone another chance at life. We should not take our organs with us; they can be used to save lives and give hope to those waiting for a transplant.
