Stress is an inevitable part of life, but its consequences are not just mood swings and mental fatigue. Continual stress makes people produce extra cortisol, a hormone that has a critical role in adapting to short-term challenges, but chronically in high quantities it tends to cause harm to the body causing lots of physical and mental disorders.
The adrenal glands produce cortisol, which helps the body control its "fight, flight, or freeze" response. Cortisol temporarily adjusts blood sugar levels, maintains blood pressure, and assists the immune system, among other functions, in short spurts. But when stress persists, cortisol remains high, and necessary functions of the body are interfered with and rendered more susceptible to disease.
According to one survey conducted by the American Psychological Association, stress negatively affects a third of Americans' physical health. Concerns are reinforced by research where studies have shown 80% of primary care visits are stress-related.
But why does stress have such a profound impact? Elevated cortisol limits the immune system's ability to fight infections, disrupts hormonal balance, and triggers inflammation. Over time, these changes can lead to serious health complications.
Do you have involuntary eye spasms? These harmless but annoying twitches often indicate elevated cortisol. The tiny muscles around the eyes are extremely sensitive to stress, contracting or spasming because of cortisol's stimulant-like effects.
Your skin often reflects what is going on inside your body, and chronic stress can cause inflammatory skin conditions. Elevated cortisol levels stimulate oil production, which exacerbates acne. It also slows down the healing process, worsens conditions like eczema, and contributes to general irritation of the skin.
It also interferes with the body's balance of salt and water, which causes fluid retention and bloating. Excess cortisol also slows down blood flow to the digestive system, which further weakens gut bacteria and causes poor digestion, excess gas, and abdominal discomfort.
High cortisol stimulates the production of insulin, which can cause blood sugar to drop, making people want to eat sugary, high-fat foods. For many, this becomes an excuse to stress-eat and gain weight. For others, the opposite is true: their appetite disappears under stress, causing them to lose weight.
If you’re noticing random bruises, elevated cortisol could be the culprit. This hormone weakens skin proteins and the walls of small blood vessels, making your skin more fragile and prone to damage.
Do you feel rundown or experience muscle aches, fatigue, or upset stomach regularly? Elevated cortisol mimics cold-like symptoms. Long-term stress also weakens the immune system, making you more susceptible to infections.

Chronic stress can damage your eyesight. Elevated cortisol disrupts blood flow to the eyes, increases eye pressure, and raises the risk of glaucoma. Symptoms like dry eyes, blurred vision, and light sensitivity are also common.
Irregular Menstrual Cycles that disrupt the menstrual period. In females, this leads to hormonal distress causing irregular or missed periods. Over time, it may also disturb fertility.
If you hear ringing, buzzing, or hissing sounds without an apparent source, stress might be the culprit. Cortisol affects the auditory system by interfering with blood flow and nerve function and could be the trigger for tinnitus.
Increased levels of cortisol contribute to inflammation that can exacerbate conditions such as arthritis and promote the development of heart disease. Chronic inflammation is also associated with mental health conditions, including anxiety and depression.
Left unchecked, high cortisol levels can lead to more than just short-term discomfort. Chronic stress has been associated with serious conditions such as heart disease, psychiatric disorders, and metabolic syndromes. A 2013 study published in JAMA Internal Medicine underlined the link between stress and physical health, with recent research in Neurobiology of Stres supporting these findings.
Managing stress and cortisol levels is essential for maintaining overall health. One effective approach is practicing mindfulness through meditation or yoga, which helps lower cortisol by calming the mind and promoting relaxation. Regular physical exercise, especially aerobic activities, helps reduce stress hormones and boosts endorphins. Prioritizing sleep is crucial, as lack of rest can increase cortisol levels; aim for 7-9 hours per night.
Another remedy is an overall balanced diet full of anti-inflammatory foods like fruits, vegetables, and whole grains that could manage cortisol production. Finally, it would prevent burnout and chronic stress if proper boundaries were set at work and in personal life.

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.
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.
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:
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.
The researchers did not have information on several factors that can influence cardiovascular disease risk, including:
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. To raise awareness about organ donation, it is important 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.
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.
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.

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.
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.
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.
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.
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.

• 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.

Anemia remains one of the least talked about threats to a safe pregnancy in India. The National Family Health Survey-5 data shows that 52.2% of pregnant women in India were anemic. This translates to at least one in two expectant mothers entering pregnancy with insufficient hemoglobin to meet her own and her baby’s needs.
Pregnant women with iron-deficiency anemia may feel unusually tired, weak or short of breath. Some women may suffer from dizziness, headaches, palpitations or reduced ability to concentrate. However, symptoms can be subtle and this is why routine antenatal screening is important even if the woman feels well.
Left unaddressed, it raises the risk of preterm birth, low birth weight, postpartum haemorrhage, and maternal fatigue severe enough to affect daily functioning and recovery after delivery.
Severe anaemia can also reduce a woman's ability to tolerate blood loss during delivery, making even an otherwise uncomplicated birth potentially more challenging.
Why pregnancy makes it worse? Well, blood volume expands by nearly 50% during pregnancy, and the growing fetus draws heavily on maternal iron stores, especially in the second and third trimesters. Most Indian women begin pregnancy with iron stores already depleted by poor dietary intake, frequent pregnancies, or heavy menstrual blood loss. So, the added demand tips many into overt anaemia.
1. Start Antenatal Care early. You should get a baseline haemoglobin test at your first antenatal visit, and repeat this each trimester or more if needed.
2. Iron and folic acid tablets must be taken in accordance with the prescription given. It is best to start with them before conceiving or as soon as possible in the pregnancy process, preferably in discussion. The dietary consumption may not always be sufficient to cater to the increased demands during pregnancy.
3. Pair iron-rich foods with vitamin C. A squeeze of lemon with dal or leafy greens meaningfully improves absorption. Indian gooseberry (amla), guava, oranges and tomatoes improve absorption of non-heme iron from plant based foods.
4. Include iron-dense foods regularly like leafy greens, jaggery, dates, legumes, eggs. If non-vegetarian, eat lean meat or fish, meat or poultry.
5. Treat underlying causes. Get heavy periods, worm infestations or unexplained fatigue evaluated before conception if possible.
6. Ask about your ferritin level, not just haemoglobin, since ferritin reveals depleted iron stores earlier.
Anaemia is not always caused by iron deficiency. B12 or folic acid deficiency, problems with haemoglobin production, infections, and many other medical conditions can also be contributing factors.

1. Do not stop iron supplements simply because you feel better. Treatment usually needs to continue for the recommended period to replenish iron stores.
2. Don't take iron tablets with tea, coffee or milk. These block absorption. Space them at least an hour apart.
3. Do not skip supplements because of nausea or constipation. Ask your doctor for alternate formulations instead of foregoing the supplements.
4. Don't assume fatigue is ‘normal pregnancy tiredness’ without a haemoglobin check. Persistent breathlessness, dizziness or a racing heart need evaluation.
5. Don't self-medicate with over-the-counter iron doses. Both too little and too much iron can cause harm.
6. Don't ignore mild anaemia on the assumption that it will ‘sort itself out’. It typically worsens as pregnancy progresses and has to be actively treated.
Anemia in women is mostly preventable and treatable early. Regular antenatal check ups, proper supplementation, balanced diet and timely treatment can go a long way in reducing its impact on the mother and baby. The key message is simple, really. Screen early, do not wait for symptoms, treat appropriately and maintain adequate iron stores throughout pregnancy.
