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.

Diabetes at 35 and diabetes at 60 are not the same. As we grow older, the way diabetes presents, the complications we worry about and even the way we treat it can change. This is why diabetes care after 60 needs to look beyond a single blood test.
HbA1c remains an important measure of average blood sugar over the previous few months. But for an older adult, it cannot be the only measure of good diabetes care.
One of the challenges with diabetes in older people is that symptoms may not always be obvious. A person may not experience the typical excessive thirst, frequent urination or unexplained weight loss, even when blood sugar levels are high.
At the same time, older adults can be more vulnerable to diabetes-related complications affecting the eyes, kidneys, nerves, heart and blood vessels. Vision problems are particularly important because loss of vision can directly affect mobility, confidence and independence.
This makes regular screening essential, even when a person feels completely well.
There is no single HbA1c cut-off that is appropriate for every older adult. Treatment goals need to consider age, overall health, cognitive function, physical function, existing complications and the person's ability to manage treatment independently. Current diabetes standards specifically recommend individualising glycaemic goals in older adults.
For example, a healthy 65-year-old who is active and independent may have very different treatment goals from an 80-year-old who is frail, has multiple medical conditions or needs help with daily activities.
The goal should be good blood sugar control without causing unnecessary harm, particularly hypoglycaemia.
As people age, kidney function can change, meals may become irregular and multiple medicines may be prescribed for different conditions. These factors can increase the risk of low blood sugar and make complex treatment plans harder to follow.
Therefore, doctors may need to review medicines regularly and simplify treatment when appropriate. The focus should be on finding a treatment plan that is effective, safe and practical for that individual.
A comprehensive diabetes review in an older adult should also consider:
The aim is not simply to produce a better HbA1c report. It is to prevent complications while helping the person remain active and independent.
Older adults with diabetes need adequate nutrition, particularly protein and other nutrients needed to maintain muscle mass. Excessive dietary restriction can sometimes do more harm than good.
Physical activity is equally important. Walking, strength exercises and balance activities, when medically appropriate, can help maintain mobility and reduce the risk of losing independence.
Diabetes management after 60 should be personalised and regularly reassessed. What is appropriate at 60 may not be appropriate at 75 or 85.
As we mark the International Day of Older Persons, the message is simple: living well with diabetes in later life is about much more than achieving a particular HbA1c.
We need to treat the person, not just the number — protecting their health, safety, dignity and independence as they grow older.

Changes in voice pitch, volume or clarity in older adults could be an early warning sign of cognitive decline, according to a new analysis.
The study, published in the Journal of Voice, found that older adults who experienced a decline in voice quality had a higher risk of cognitive impairment or dementia than those without a voice disorder.
The study tracked the health of more than 833,000 older Americans. Researchers found that people with a voice disorder had a 58% higher risk of cognitive impairment or dementia than those without voice problems.
The risk was even higher among people who had both a voice disorder and hearing loss, a well-recognized risk factor for Alzheimer’s disease.
A brief episode of hoarseness does not mean that a person is developing dementia.
However, persistent or noticeable changes in the voice, particularly when accompanied by hearing loss, may warrant a medical evaluation and, where appropriate, an assessment of cognitive health.
“We found the strongest link with dementia among patients experiencing a voice disorder and hearing loss,” said study author Dr. Robert Sataloff, a professor and chair at Drexel University’s College of Medicine.
“Importantly, we found that those with a voice disorder and no hearing loss were at greater risk than patients who experience hearing loss only. It may be valuable for many of these patients to talk with an otolaryngologist who can arrange a cognitive assessment to help patients develop an appropriate care plan.”

The researchers speculate that voice disorders may contribute to cognitive decline by limiting social interaction, which can also be affected by hearing loss.
People who have difficulty speaking or hearing may avoid social gatherings or group activities because they feel embarrassed or uncomfortable about their limitations. However, social engagement can help keep the ageing brain active by providing ongoing mental stimulation.
“If you have a voice disorder that impacts how your voice sounds or if it’s painful when you attempt to talk or sing, it’s only natural to participate less often in brain-supporting social or other engaging activities,” Dr. Sataloff said.
Speaking less may mean less social and cognitive stimulation, which could potentially contribute to dementia risk. However, the researchers also noted another possibility: changes in the brain associated with dementia could themselves contribute to voice problems. However, this has not been directly studied.
Most people with voice disorders will not go on to develop Alzheimer’s disease. Voice changes can have several other causes, including thyroid problems and cysts on the vocal cords, some of which can be treated effectively.
Speech therapists can also help people with impaired speech communicate more effectively and confidently.
Seeking medical attention for persistent voice changes can therefore help identify treatable causes and determine whether further evaluation, including a cognitive assessment, is needed.

As the 2026-27 flu season begins in the US, doctors are reminding people that influenza can cause more than just cough, fever and a runny nose. Symptoms can come on suddenly and affect the entire body, with some patients also developing gastrointestinal symptoms.
During the 2025-2026 flu season, influenza caused at least 32 million illnesses, 390,000 hospitalizations and 24,000 deaths in the US, according to preliminary data from the Centers for Disease Control and Prevention (CDC).
According to the World Health Organization, from February through August 2026, influenza A(H1N1)pdm09, A(H3N2) and influenza B viruses circulated across regions. Influenza A viruses predominated in most regions, while influenza B dominated in Northern and Western Africa, North America and Eastern Asia.
While it is too early to know what the season ahead will look like, knowing the range of flu symptoms can help people recognize the infection. These include the classic symptoms of sudden fever, chills, body aches and extreme fatigue, as well as vomiting and diarrhea in some children.

Influenza commonly affects the nose, throat and lungs, but its symptoms can be widespread.
The most common symptoms include:
Family physician Carlos Galindo at Texas Health Family Care said fever, chills and body aches are the classic flu combination. People may also develop a sore throat, runny nose and headache, according to the American Medical Association.
Unlike the gradual tiredness that can accompany a cold, flu-related fatigue can be intense.
Galindo described it as significant lethargy and malaise, with some patients feeling completely drained.
One of the key features doctors want people to recognize is how quickly influenza can make someone feel unwell.
Family physician Christopher Zipp of Atlantic Health in Morristown, New Jersey, said flu symptoms can develop over just a few hours, with fever, chills and body aches appearing suddenly.
However, flu symptoms can overlap with those of other respiratory infections, so symptoms alone cannot always confirm that someone has influenza.

Flu symptoms can also differ between children and adults. While fever, chills, body aches and respiratory symptoms are common, children may also develop gastrointestinal symptoms such as vomiting and diarrhea.
These symptoms can occur alongside cough, sore throat or other signs of respiratory infection.
For most people, influenza is an unpleasant but temporary illness. However, it can sometimes lead to complications such as pneumonia and hospitalization, particularly in people with underlying health conditions.
Symptoms that become severe or worsen rather than improve warrant medical attention, especially among people at higher risk of complications.
In the US, many flu cases are seen between January and March, although influenza can circulate outside the peak season as well.
Doctors generally recommend flu vaccination around September or October to build protection before activity increases. It takes about two weeks for the body to develop protection after vaccination. Flu vaccination has been shown to reduce flu-related doctor visits by about 40% to 60%.
