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.

Oral Rehydration Solution (ORS) is one of the simplest yet most effective life-saving solutions that every household should keep readily available, doctors said on World ORS Day.
Observed every year on July 29, World ORS Day raises awareness about the importance of ORS—a scientifically formulated mix of glucose and electrolytes, including sodium and potassium—that helps prevent and treat dehydration caused by diarrhea, vomiting, fever, heat, and excessive sweating.
First introduced in 1969, ORS has transformed the treatment of dehydration worldwide. Since 2003, the World Health Organization (WHO) and UNICEF have recommended a low-osmolarity ORS formula, which improves fluid absorption and reduces the need for intravenous fluids. Today, ORS remains the gold standard for preventing and treating dehydration, particularly in children and people living in resource-limited settings.
Dr. Ranjana Bhatt, Associate Director - Internal Medicine, Paras Health, Panchkula, told HealthandMe that ORS is not a medicine that cures the underlying illness but is designed to prevent and correct dehydration.
Dehydration occurs when the body loses more water and electrolytes than it takes in, most commonly due to diarrhea or vomiting. It can develop rapidly, especially in young children, older adults, and people with chronic illnesses.
ORS works through a well-established biological process in the small intestine. It contains the right balance of glucose and sodium, which are absorbed together through special proteins called sodium-glucose cotransporters (SGLTs). As sodium enters the bloodstream, water follows, allowing the body to rehydrate efficiently.
This mechanism makes ORS more effective than plain water—and often more effective than many commercial sports drinks—for replacing lost fluids and electrolytes quickly and safely.
"Recognizing the early signs of dehydration, such as excessive thirst, dry mouth, dizziness, reduced urination, and unusual fatigue, and starting ORS promptly can prevent serious complications. On ORS Day, we encourage every family to make ORS a household essential and use it appropriately while seeking timely medical care whenever symptoms are severe or persistent," Dr. Bhatt said.
Dr. Amit Prakash Singh, Consultant - Internal Medicine, CK Birla Hospital, Delhi, told HealthandMe that ORS is one of the simplest, most affordable, and most effective ways to prevent dehydration.
"ORS is accessible for almost everyone, and the product is recommended by the World Health Organization to start treating dehydration caused by diarrhea at home. Having ORS packets at home enables treating dehydration without going to the doctor first and potentially avoiding hospitalization," he said.
Besides diarrhea, ORS can help replace fluids and electrolytes lost due to:
"ORS is not just for diarrhea. Whenever there is a lot of fluid loss or electrolyte loss, ORS can be used. ORS can be consumed for vomiting due to gastroenteritis, food poisoning, or viral infection (provided the person can sip small amounts repeatedly)," Dr. Singh said.
Doctors caution that ORS only replaces lost fluids and electrolytes—it does not treat the underlying disease.
It may help prevent dehydration after fever, vomiting, or excessive sweating, but it is not a treatment for abdominal pain, acidity, indigestion, constipation, gastritis, or irritable bowel syndrome (IBS). Persistent or severe symptoms should always be evaluated by a healthcare professional, Dr Singh said.

Liver disease is unusual among serious conditions in that it can progress significantly without producing symptoms that would prompt most people to seek medical attention. Hepatitis, which is inflammation of the liver, is the most common starting point for that progression.
It may be caused by viral infections including Hepatitis B and Hepatitis C, excessive alcohol consumption, fatty liver disease, certain medications, or autoimmune conditions. In many cases, the person carrying it feels entirely well while damage accumulates over months and years.
The liver does regenerate, but that capacity has limits. When inflammation persists, healthy liver cells are progressively replaced by scar tissue, a process called fibrosis.
Continued scarring eventually produces cirrhosis, where the liver loses its structural integrity and its ability to perform the functions the body depends on it for, such as processing toxins, producing proteins involved in blood clotting, regulating metabolism, and supporting digestion. At this stage, the damage is largely irreversible.
The timeline from hepatitis to cirrhosis typically spans years or even decades, which is precisely what makes delayed diagnosis so consequential. Each year of untreated inflammation is a year of accumulated scarring.
By the time cirrhosis produces obvious symptoms such as jaundice, abdominal swelling from fluid accumulation, internal bleeding from enlarged veins in the oesophagus, cognitive changes from toxin build-up, kidney involvement, the disease has already reached an advanced stage. Cirrhosis also carries a significantly elevated risk of liver cancer.
The clinical picture is meaningfully better when liver disease is identified early. Effective antiviral medications can control chronic Hepatitis B and cure most cases of Hepatitis C, substantially reducing the risk of progression.
Fatty liver disease, when caught before significant fibrosis has occurred, can often be reversed through weight management, blood sugar control, reduced alcohol intake, and consistent physical activity. These interventions are accessible, evidence-based changes that work when applied before the disease has advanced.
Screening is where early identification happens. Blood tests measuring liver enzymes and imaging studies can detect liver inflammation and early fibrosis well before symptoms appear.
For individuals with diabetes, obesity, a family history of liver disease, a history of blood transfusions, or other known risk factors, periodic liver assessment is a practical and important part of routine care rather than an optional precaution.
The pattern that gastroenterologists consistently encounter is patients presenting with advanced liver disease who had risk factors identifiable years earlier. Hepatitis B and C are both detectable through simple blood tests.
Fatty liver shows up clearly on ultrasound. The window for effective intervention exists, and it is considerably wider earlier in the disease than most people assume when they have never been tested.
This draws attention to a disease that carries a substantial global burden but remains widely undertreated because it does not announce itself. For anyone with known risk factors, or who has never had their liver function assessed, the appropriate response to that is a conversation with a physician, before symptoms, rather than after.

Smoking, diabetes, high blood pressure, high cholesterol, and obesity have always been recognized as major risk factors for heart disease.
New research has emerged saying these preventable conditions may do more harm than simply contribute to plaque buildup in the arteries. They may also encourage the formation of the most dangerous type of plaque, the kind that is most likely to rupture and trigger a massive heart attack.
The findings, presented at the European Society of Cardiology (ESC) Congress 2026, show that people with a greater number of modifiable cardiovascular risk factors were more likely to have widespread coronary plaque.
They may also have unstable and vulnerable plaques that can suddenly rupture, disrupting blood flow to the heart.
Researchers analyzed coronary artery imaging data to understand how both modifiable and non-modifiable cardiovascular risk factors affect the characteristics of plaque.
The study found that patients with a higher burden of modifiable risk factors had plaques distributed across all three major coronary arteries.
More importantly, these individuals were more likely to develop lipid-rich plaques with thin fibrous caps, a trait of vulnerable plaques that are more likely to rupture.
On the other hand, people whose risk profile was dominated by non-modifiable factors, such as age or genetics, tended to have more stable plaque types.
"Our findings suggest that modifiable cardiovascular risk factors are associated not only with a greater amount of coronary plaque but also with more vulnerable plaque characteristics that are linked to future heart attacks," the researchers said.
Some plaques gradually harden and remain relatively stable for years, causing slow narrowing of the arteries. Others contain large amounts of fat covered by a very thin protective layer known as a fibrous cap.
These unstable plaques can rupture unexpectedly, prompting blood clots to form and suddenly block an artery, leading to a heart attack or stroke.
According to the researchers, individuals with multiple preventable cardiovascular risk factors were significantly more likely to have these high-risk plaques.
Smoking chronically damages the inner lining of blood vessels, making it easier for cholesterol deposits to accumulate while also promoting inflammation and blood clot formation.
High blood pressure places constant stress on artery walls, accelerating plaque development and increasing the likelihood of rupture.
When several of these risk factors occur together, their harmful effects can compound, increasing both the quantity of plaque and likelihood to rupture.

Atherosclerosis is a chronic condition in which fatty deposits made up of cholesterol, inflammatory cells, calcium, and other substances accumulate inside artery walls.
Over time, these deposits narrow the arteries and reduce blood flow to vital organs. The condition often develops silently over decades before causing symptoms.
If a plaque ruptures, a blood clot can rapidly block blood flow, resulting in a heart attack or stroke. Smoking, diabetes, high blood pressure, obesity, and elevated LDL ("bad") cholesterol are among its leading preventable causes.
The researchers said the study highlights the importance of early identification and management of modifiable cardiovascular risk factors through smoking cessation, blood pressure control, diabetes management, cholesterol-lowering treatment, regular physical activity, a healthy diet, and maintaining a healthy weight.
