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.

Insulin resistance is a condition in which the body cannot effectively use insulin. Shockingly, this condition is now being linked to first-trimester miscarriages, especially in women with PCOS, with lab markers such as HbA1c and fasting insulin offering early clues. Therefore, it is essential for women to take charge of their health and maintain their blood sugar levels within the recommended range, as per Dr Sushruta Mokadam, Senior Consultant Obstetrician & Gynaecologist, Motherhood Hospital, Kharadi, Pune. The expert went on to talk about other aspects of the same, detailing just how first trimester miscarriages could be a consequence of ignoring high blood sugar or insulin resistance.
Currently, there is a surge in cases of miscarriages during the first trimester, which is raising concern among experts. This may be due to undiagnosed insulin resistance. Yes, that’s right—miscarriage is not only caused by infections, hormonal imbalance, or blood clotting disorders, but also by insulin resistance. Many women fail to pay attention to insulin resistance, which affects how the body processes sugar and plays a major role in causing hormonal imbalance. Women with Polycystic Ovary Syndrome (PCOS) are at a higher risk, as metabolic dysfunction can lead to miscarriage. Many women are experiencing repeated early pregnancy loss but are not screened for insulin resistance, leading to missed opportunities for early intervention.
Miscarriage and insulin resistance link: Insulin resistance occurs when the body’s cells do not respond properly to insulin, leading to higher blood sugar and insulin levels. This imbalance can impact ovulation and egg quality and interfere with the implantation of the embryo. In early pregnancy, it may affect placental development, increasing the risk of miscarriage in the first trimester. In women with PCOS, insulin resistance is commonly present, even in those who are not overweight.
High insulin levels can lead to increased androgen (male hormone) production, further affecting reproductive health. This hormonal imbalance can make it difficult for a pregnancy to be sustained, especially in the early weeks, which may result in miscarriage. Lab tests such as HbA1c (which reflects average blood sugar levels over time) and fasting insulin levels can help identify at-risk women. Even subtle elevations in these markers, including those within the upper-normal range, can indicate underlying metabolic dysfunction that may increase the chances of miscarriage.
What to do?
Pregnant women should opt for regular screening, manage blood sugar levels, eat a balanced diet, and exercise daily before planning pregnancy. Even during pregnancy, they should stay in touch with an expert who can guide them throughout the process.

Blood pressure is one of the most important, yet overlooked, aspects of a healthy individual. Little do people realise that the force at which blood presses against the walls of the arteries can have a serious impact on long-term health—heart attack or stroke, for instance. Current guidelines from the American Heart Association state that adults should aim for a blood pressure reading of 130/80 millimetres of mercury (mm Hg). Some experts also say that this target is a little too aggressive for people who are prone to the side effects of blood pressure medication, such as falls and dizziness. But what would be the ideal blood pressure reading for older adults? Harvard Health experts have just answered this question.
According to recent studies, an intensive reduction in blood pressure in people aged over 60 is not only safe but is also associated with better outcomes than less aggressive treatment. According to a 2025 review, four randomised controlled trials were compared using two different strategies to control systolic blood pressure. The first aimed for a lower target, while the other strategy aimed for a higher systolic pressure. The trial included 2,600 people aged 75 years and older. Compared with a less aggressive strategy, there was a 39 per cent reduced risk of heart problems such as heart failure, heart attack, or stroke. There was also a 45 per cent lower risk of heart disease-related deaths.
Additionally, researchers noted no differences in the rates of adverse events such as fractures, low blood pressure, cognitive decline, or falls. Upon expanding the analysis, the same conclusions held true for people aged 70 years and above.
The risk of hypertension rises significantly with age. Among ageing adults, it is known as essential hypertension, as it helps deliver a sufficient amount of blood to the brain. With age, the blood vessels become less flexible and stiffer. Therefore, to reach the brain, an extra push is needed—as a result, systolic blood pressure can rise to as high as 150 mm Hg in people aged 65 years and above.
Doctors, however, are reconsidering their approach to hypertension treatment in older adults. The recent findings suggest that many older people should aim to keep their systolic pressure below 130 mm Hg. This may require a combination of lifestyle changes and medication.
According to experts, one medication may not be sufficient to achieve ideal blood pressure. A single drug usually works well to lower blood pressure by an average of 5 to 10 points. Using a lower dose of two different blood pressure medicines is more effective than maximising the dose of one drug. This approach is also less likely to result in side effects.

The relationship between chronic stress and liver health is a complex physiological loop driven largely by cortisol, the body’s primary stress hormone. While the liver is often viewed as a detox organ, it is highly responsive to hormonal signals, especially during prolonged stress. But at a time when competition is at its all-time peak in every aspect of life, be it work or school, it is a no-brainer that stress levels are peaking across age groups. That being said, Dr. Tushar Madake, Consultant, Department of Transplant Hepatology at Ruby Hall Clinic, Pune, spoke about the impact of high cortisol on the liver.
When stress becomes chronic, the adrenal glands continuously release cortisol. The liver, rich in glucocorticoid receptors, responds by shifting into a survival mode. In short-term situations, this helps by releasing glucose into the bloodstream for quick energy. However, when stress persists without physical activity, this constant signal disrupts normal metabolism.
One major effect is increased glucose production, where the liver generates sugar from non-carbohydrate sources. Over time, this leads to consistently high blood sugar and forces the pancreas to produce more insulin, eventually contributing to insulin resistance. At the same time, cortisol promotes the release of fatty acids into the bloodstream. The liver absorbs these fats but struggles to process and export them efficiently, leading to elevated triglycerides and unhealthy cholesterol levels.
Stress also drives fat storage in the abdominal region and within the liver itself. This can result in fatty liver disease, even in individuals without poor dietary habits. As fat accumulates, inflammation follows. Liver immune cells release inflammatory substances, creating oxidative stress that damages liver cells. Additionally, when the liver is overloaded with managing excess glucose and fat, its ability to detoxify the body declines. Hormone balance, toxin clearance, and medication metabolism are all affected.
Stress can also impair bile flow, which is essential for fat digestion and toxin removal. Reduced bile movement further worsens internal imbalance. Ultimately, chronic stress keeps the liver in a constant state of overdrive, leading to long-term metabolic strain, inflammation, and gradual liver dysfunction.
