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.

Signs That High Cortisol Is Stressing Your Body

Persistent Eye Twitches

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.

Skin Breakouts and Sensitivity

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.

Frequent Bloating and Digestive Issues

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.

Weight Fluctuations

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.

Unexplained Bruising

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.

Cold Symptoms That Won’t Go Away

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.

Vision Problems

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

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.

Tinnitus or Persistent Ringing in the Ears

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 Inflammation and Chronic Disease

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.

Long-term Consequences of Increased Cortisol

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.

Ways Managing Stress and Cortisol Levels

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.

Indians are facing an increasing burden of heart diseases, and mortality is rising faster compared to other countries. A top US cardiologist has now shared the major risk factors that range from genetics to obesity to pollution.

Cardiovascular diseases (CVDs) cause nearly 31 per cent of all deaths in India, according to the latest Sample Registration Survey (SRS) 2021-2023 data from the Registrar General of India, released in September 2025.

The SRS report highlighted cardiovascular diseases as the leading cause of death, especially among adults over 30.

Speaking exclusively to HealthandMe, Dr. Sripal Bangalore, Professor of Medicine at New York University School of Medicine, highlighted the key reasons why India is seeing a huge burden of heart diseases.

"I think it’s a combination of traditional and non-traditional risk factors. Globally, we are seeing the burden of obesity increasing, and specifically in India, genetic factors and non-traditional risk factors also play a role," Dr. Sripal said.

"There is a growing investigation into lipoprotein(a) and other causes of cardiovascular disease (in India). Obesity is a major risk factor, and I’m sure stress and pollution also add to it, with more and more data supporting these links," he added.

Data from the World Heart Federation showed that heart disease kills 28.6 lakh Indians every year. In the recent past, India has also been seeing a significantly higher rate of heart attacks and related deaths, even in children as young as 12 years old.

What Factors Are Driving This Trend

"I think we need to know that part of it tends to be non-traditional, because in the Western world most of it is explainable by traditional risk factors like hypertension, diabetes, and hypercholesterolemia," Dr. Sripal said.

"What we see in India is that it is less about those risk factors, but more about non-traditional ones, including potentially genetic factors and lipoprotein(a)," the doctor added.

The Indian-origin interventional cardiologist also cited lifestyle factors such as stress and pollution that are significantly adding to the increased risk of cardiovascular events in the country.

AHA 2026 Cholesterol Guidelines: Relevance For India

Recently, the American Heart Association (AHA) released cholesterol guidelines, which stressed the importance of early screening, starting with teenagers.

The guidelines call for early intervention through early screening and healthy lifestyle changes, starting from childhood.

It recommends:

• Children (9-11 years): Cholesterol screening if never done before.
• Adults (30-79 years): Evaluate 10- and 30-year ASCVD risk to determine the need for early intervention

"India is a good example where LDL levels (bad cholesterol) may not be very high, like in the Western world. Many times, HDL cholesterol (good cholesterol) tends to be lower, and there are other risk factors, including lipoprotein(a), which seems to be elevated here," Dr. Sripal said.

How To Improve Heart Health

The doctor also explained whether overall diet quality matters more than just cholesterol intake.

"Diet adds to the totality of everything that we do, including increasing the risk of obesity. Cholesterol may explain some part of it, but having a heart-healthy diet is critically important," Dr. Sripal said.

The cardiologist highlighted the need to increase the intake of fruits and vegetables, as consuming natural foods is critically important.

Importantly, he also emphasized at least making sure that you have a lipid panel to check your cholesterol levels.

"We are assuming that you are staying healthy and not smoking. Checking blood pressure, it depends on your age, but at least once a year, checking your lipid panel would be critically important," Dr. Sripal told HealthandMe.

As a cardiologist, he shared that to boost heart health, the key is

• to make sure that you lead a healthy lifestyle,
• stay away from smoking,
• increase physical activity,
• reduce stress.

"Pollution is one factor, and I think we can all do our part to make sure that we don’t contribute more to environmental pollution," he noted.

While India’s Ministry of Environment, Forest, and Climate Change (MoEFCC) enforced a nationwide ban on identified single-use plastic (SUP) items from July 1, 2022, a new survey showed that violations continue to persist across major cities in the country, raising significant health and environmental risks.

The survey of 560 locations by Toxics Link -- an Indian environmental research and advocacy organization -- showed that 84 percent of sites across Delhi, Mumbai, Guwahati, and Bhubaneswar still use or sell banned plastic items.

Bhubaneswar recorded the highest availability of banned SUPs at 89 percent of survey locations, followed by Delhi at 86 percent, Mumbai at 85 percent, and Guwahati at 76 percent.

The survey noted that high use among street food vendors, juice shops, coconut water sellers, vegetable vendors, and ice cream parlours.

"The continued presence of banned plastic items in a majority of locations suggests that enforcement remains inconsistent,” said Ravi Agarwal, Director of Toxics Link.

“Unless implementation improves and the supply of these products is controlled, the ban will not effectively address plastic littering and pollution,” he added.

How Plastics Can Harm Your Body

Plastic carry bags, disposable plastic cutlery, cups, plates, and straws often contain chemicals like BPA and phthalates, which can interfere with the body’s hormonal balance.

BPA is an industrial chemical used to make certain plastics and resins, and its exposure has been linked to several health conditions, including an increased risk of high blood pressure.

Phthalates, another group of chemicals used to make plastics more flexible, have been found to disrupt the endocrine system, leading to potential health issues.

Studies have proven that BPA and phthalates can mimic the body’s hormones, particularly estrogen. This interference can disrupt the normal functioning of the cardiovascular system, leading to increased blood pressure.

Plastics also contain some highly toxic chemicals, such as flame retardants, per- and polyfluoroalkyl substances (PFAS), that can migrate into the environment and into human bodies.

According to a report by WWF, an average person could be ingesting approximately 5 grams of plastic every week.

Scientific studies have proven that the health effects of plastics include cancer or changing hormone activity (known as endocrine disruption), which can lead to reproductive, growth, and cognitive impairment.

Recent evidence also indicates that humans constantly inhale and ingest microplastics through contaminated seafood, including fish and shellfish.

In addition, microplastics have been found in tap water, bottled water, and even commonly consumed beverages, such as beer and salt.

How to Reduce the Disease Risks?

The UNDP urges individuals, organizations, and governments to work together to

• manage plastic waste,
• reduce plastic usage,
• transition to a more sustainable and resilient environment.

Other options include

• Opting for BPA-free and phthalate-free options
• Switching to reusable water bottles, plates, and cutlery made from glass, stainless steel, or other safe materials can significantly reduce exposure to harmful chemicals.
• Avoid exposing plastic bottles or lunch boxes to high temperatures, as heat can accelerate the leaching of chemicals into the water.

While a weakened immune system and fear of complications once denied people with HIV access to organ transplants, doctors at a Delhi hospital have now challenged the idea with a successful kidney transplant surgery on a 43-year-old HIV-positive patient from Ethiopia.

According to the team of doctors from the Max Super Speciality Hospital, Patparganj, who successfully performed the complex living donor kidney transplant, advancements in antiretroviral therapy and transplant protocols have made such procedures increasingly safe in carefully selected cases.

“HIV is no longer a barrier to organ transplantation when managed appropriately,” said Dr. Ravi Kumar Singh, Senior Consultant, Nephrology and Transplant Physician at Max Hospital, Patparganj.

“With strict selection criteria and coordinated multidisciplinary care, patients with well-controlled HIV can achieve outcomes comparable to the general transplant population.”

Kidney Transplant In HIV Positive Patient

The patient, who had been living with HIV for 10 years, developed end-stage renal disease 3 years ago and has been dependent on regular dialysis since then.

Before the surgery, the patient underwent extensive evaluation to ensure optimal control of HIV, including a stable immune profile and undetectable viral load.

The patient’s 33-year-old wife donated one of her kidneys. Compatibility testing confirmed matching blood groups and a negative cross-match, enabling the team to proceed with the transplant.

“Kidney transplantation in patients with HIV requires a highly meticulous and coordinated approach, given the complexities of balancing immunosuppression with ongoing antiretroviral therapy,” said Dr. Paresh Jain, Senior Director, Urology, Robotic Surgery & Renal Transplant.

“In this case, careful pre-transplant evaluation, precise surgical execution, and close post-operative monitoring were critical to ensuring a successful outcome. This procedure reflects how advances in transplant science and surgical expertise are enabling us to safely expand access to life-saving transplants for patients who were once considered high-risk,” he added.

Following the transplant, the patient has shown encouraging recovery, has been taken off dialysis, and is gradually returning to normal daily activities, the doctors said. The patient also continues on a carefully monitored regimen of immunosuppressive and antiretroviral therapy, they added.

Can People With HIV Get A Transplant?

With advancements in antiretroviral therapy (ART), enabling people to live longer, HIV has now become a chronic, manageable condition. However, the HIV positive patients are now more likely to die from end-stage organ disease than from AIDS-related infections.

As per the US National Institutes of Health, people with HIV can successfully donate or receive transplanted organs with reasonable success rates.

However, health care providers must consider and monitor potential drug interactions, kidney and liver function, and HIV viral suppression in people with HIV receiving a transplant.

Further, the NIH advised HIV positive patients to continue taking all prescribed HIV medicines before and after transplant.
