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.

New research suggests that menopause may be linked to a loss of grey matter in the brain, which could help explain why women face a higher risk of dementia compared to men. Scientists from the University of Cambridge analysed data from 124,780 women to explore how menopause affects the brain and whether hormone replacement therapy (HRT) might help protect against cognitive decline.

Menopause May Be Linked to Changes in Brain Structure

The researchers found that menopause was associated with reduced levels of grey matter, an essential part of the brain involved in thinking, memory, emotional processing and movement. The findings also noted that this stage of life is often accompanied by anxiety, depression and sleep problems. Previous research has already shown that menopause can affect cognitive abilities such as attention, language, learning and memory.

How Menopause And HRT Affect Thinking Speed

Published in the journal Psychological Medicine, the research divided participants into three groups: women who had not yet reached menopause, post-menopausal women who had never used HRT, and post-menopausal women who were taking HRT. Participants answered questions about sleep patterns, anxiety and depression, and some completed cognitive tests measuring memory and reaction time.

Around 11,000 women also underwent magnetic resonance imaging (MRI) scans, allowing scientists to closely examine brain structure. On average, menopause began at age 49 among the participants, and women who started HRT typically began treatment at around the same age.

Sleep, Fatigue and Mental Health Changes

The findings showed that post-menopausal women were more likely to struggle with insomnia, get less sleep overall and feel more fatigued. Interestingly, women using HRT reported the highest levels of tiredness across all three groups, even though they slept for a similar amount of time as those not taking HRT.

All post-menopausal women, regardless of whether they were using hormone therapy, reported greater fatigue compared to women who had not yet experienced menopause. Researchers also observed that this stage of life had an impact on cognitive function.

Dr Katharina Zuhlsdorff, from the psychology department at the University of Cambridge, explained: “As we age, our reaction times naturally slow down. This happens to both women and men and is part of normal ageing. You might still reach the right answer to a quiz question, but younger people tend to respond faster. Our findings suggest menopause speeds up this slowing process, while HRT seems to slow it down slightly.”

Brain Regions Linked to Memory and Emotion Affected

The study identified significant reductions in grey matter volume among post-menopausal women. These changes were seen in the hippocampus, which plays a key role in learning and memory, the entorhinal cortex, which supports memory formation and spatial awareness, and the anterior cingulate cortex, which helps regulate attention and emotions.

Menopause As A Period of Increased Vulnerability

Professor Barbara Sahakian, the senior author of the study from the department of psychiatry, said: “The brain areas where we observed these changes are the same regions commonly affected by Alzheimer’s disease. Menopause may make women more vulnerable later in life. While it does not explain everything, it could help clarify why dementia affects nearly twice as many women as men.”

Michelle Dyson, chief executive of the Alzheimer’s Society, noted that women account for roughly two-thirds of people living with Alzheimer’s disease in the UK. “Although we do not yet fully understand why women are more affected than men, hormones are thought to play a role,” she said.

“This large-scale study strengthens evidence that menopause has an impact on the brain, including physical changes such as reduced brain volume. However, without long-term follow-up to see whether participants later develop dementia, we cannot be certain that these menopause-related brain changes directly increase dementia risk.

“There are steps people can take today to lower their dementia risk, including regular exercise, avoiding smoking and cutting back on alcohol. Anyone concerned about themselves or a loved one can use the Alzheimer’s Society dementia symptoms checklist as a starting point before speaking to a GP.”

The research also found that women taking HRT were more likely to report mental health challenges. However, the analysis suggested these women already had poorer psychological wellbeing before starting hormone treatment.

Dr Christelle Langley, from the psychiatry department, said: “Menopause is something most women will experience, and it can be a major life change whether or not HRT is used. During this time, healthy habits such as staying active, exercising regularly and eating a balanced diet become especially important to help reduce some of its effects.”

Dr Louise Newson, a GP and women’s hormone specialist, added: “Many women notice changes in memory and concentration around menopause. This study suggests these symptoms may have a biological explanation rather than being brushed off as stress or ageing, highlighting menopause as a key window for protecting brain health and providing personalised care.”

More than 10 million adults, young people, and children in the UK are currently living with arthritis, according to a 2025 report by Arthritis UK. The NHS states that osteoarthritis is the most common form of the condition nationwide.

As per Cleveland Clinic, osteoarthritis develops gradually as joints become stiff and painful due to wear and tear. Symptoms can vary depending on the joint affected and the extent of damage, but pain, swelling, and reduced movement are common. While medication is often prescribed to manage symptoms, the NHS cautions that some commonly used treatments can carry health risks if taken long-term or without proper guidance.

One of the most frequently used pain relief options is non-steroidal anti-inflammatory drugs, commonly known as NSAIDs.

What Are NSAIDs?

NSAIDs, or non-steroidal anti-inflammatory drugs, are commonly prescribed by GPs to help relieve pain, swelling, and inflammation. They are available in several forms, including tablets, capsules, suppositories, creams, gels, and injections. Some NSAIDs can be purchased over the counter, while stronger versions require a prescription.

These medicines are often relied upon for day-to-day pain relief by people with osteoarthritis, particularly during flare-ups.

NHS Warning: Who Should Be Cautious When Using NSAIDs?

The NHS advises that NSAIDs may not be suitable for everyone. Extra caution is recommended for people with asthma, a history of stomach ulcers, angina, or those who have previously experienced a heart attack or stroke. The NHS also advises that individuals taking low-dose aspirin should always consult their GP before using NSAIDs.

Long-term or incorrect use can increase the risk of stomach bleeding, cardiovascular problems, and kidney issues, making it important to review pain management plans regularly.

Can Natural Compounds Like GOPO Support Joint Health?

Consultant Rheumatologist Dr Rod Hughes explains that natural compounds are increasingly being explored as supportive options for joint health.

“Natural compounds derived from plants have long been used in both traditional and modern medicine to support joint health. One such compound is GOPO, which is derived from rose hips (Rosa canina). Research indicates that GOPO can help relieve joint pain due to its anti-inflammatory properties,” he says.

“Rather than simply masking symptoms, GOPO works by helping to regulate the body’s inflammatory response, which is a key driver of joint stiffness, swelling, and discomfort. It offers a promising alternative to traditional painkillers, with fewer risks of side effects, making it a more sustainable option for managing joint discomfort.”

Lifestyle Changes Proven To Ease Osteoarthritis Pain

According to Dr Hughes, lifestyle measures form the foundation of osteoarthritis management.

“Lifestyle choices play a central role in relieving osteoarthritis pain and helping people stay active,” he explains. “Research shows that regular, gentle exercise supported by physiotherapy, such as walking, swimming, and yoga, can be highly effective.”

“These activities help keep joints mobile and strengthen the muscles and ligaments that support them, which reduces stiffness and eases pressure on painful joints. It is also important to balance activity with rest to avoid flare-ups caused by overuse.”

Why Weight Management Matters For Joint Health

Weight management is another key factor in controlling osteoarthritis symptoms. “Maintaining a healthy body weight is especially important,” says Dr Hughes. “Extra weight places additional load on joints, particularly the knees and hips, which can worsen pain and accelerate joint damage. Even modest weight loss has been shown to significantly reduce pain and improve mobility.”

How Diet Influences Inflammation And Joint Pain

Interestingly, diet can also play a role in managing inflammation linked to osteoarthritis. “Eating plenty of fresh fruit and vegetables, whole grains, nuts, and seeds, along with at least two portions of oily fish each week, provides antioxidants and omega-3 fatty acids that help reduce inflammation and protect against cell damage,” Dr Hughes explains.

“In my practice, I often recommend combining these dietary changes with natural supplements such as turmeric or GOPO to provide additional support for joint health.”

Reducing Reliance On Long-Term NSAIDs Safely

For patients hoping to reduce their dependence on NSAIDs, Dr Hughes stresses the importance of medical supervision.

“Any reduction in NSAIDs should be done gradually and under the guidance of a healthcare professional. This helps ensure pain remains well controlled while avoiding sudden flare-ups or withdrawal issues,” he says.

“By combining regular movement, physiotherapy, supportive nutrition, and appropriate natural supplements, many patients can take a more balanced approach to managing chronic joint pain. Over time, these strategies may allow people to rely less on medication while maintaining a good quality of life.”

A doctor has cautioned that certain people may need to cut back on their favourite fruits if they are taking specific heart or blood pressure medicines. Ignoring this advice could lead to a serious but preventable health issue. Speaking during a past appearance on ITV’s This Morning, as reported by the Mirror, GP Dr Chris Steele explained that some prescribed drugs can react poorly with everyday foods. Eating these foods in large amounts may interfere with how the medication works and, in some cases, cause dangerous side effects.

He drew attention to two common fruits that many households keep on hand. The doctor warned that anyone taking medicines known as ACE inhibitors should avoid bananas and oranges. During the interview, he said: “Bananas are high in potassium, which is not suitable for certain medications. People taking ACE inhibitors such as captopril, enalapril, fosinopril, and others should try not to eat bananas or oranges.”

ACE inhibitors are used to lower blood pressure and treat heart failure by relaxing and widening blood vessels, allowing blood to circulate more easily. They are often prescribed as a first-line treatment for high blood pressure, heart failure, and some kidney conditions, though regular monitoring is needed to watch for possible side effects.

What Causes High Blood Pressure?

High blood pressure, also known as hypertension, occurs when blood pushes too forcefully against artery walls. Over time, this can damage blood vessels as well as vital organs such as the heart, brain, and kidneys. The condition often has no obvious symptoms, but it can increase the risk of heart attacks, strokes, kidney failure, vision problems, and aneurysms. Constant pressure makes the heart work harder, which may eventually lead to heart failure or thickening of the heart muscle, according to the Mayo Clinic.

Hypertension is usually linked to lifestyle factors like a high-salt diet, excess weight, lack of physical activity, and smoking. Age, genetics, and underlying health problems such as kidney disease also play a role. The condition develops when pressure inside the arteries rises, sometimes due to stress, hormonal changes, or long-term poor eating habits.

Why Are Blood Pressure Patients Being Advised To Avoid These Fruits?

Bananas, along with oranges and some salt substitutes, contain high levels of potassium. When combined with ACE inhibitors, these foods can cause potassium levels in the blood to rise too much. Mild increases may lead to symptoms such as stomach pain, diarrhoea, nausea, or vomiting. However, many people do not notice any symptoms until potassium levels become dangerously high, which can increase the risk of chest pain, heart palpitations, and an irregular, rapid, or fluttering heartbeat.

Patients are advised to inform their GP if they are taking potassium supplements or diuretics alongside blood pressure medication. Those on ACE inhibitors should avoid eating large quantities of foods that are high in potassium.

The NHS advises people in the UK to aim for five portions of fruit and vegetables each day. Since all fruits contain some potassium, no option is completely risk-free when eaten in excess. That said, some fruits are much lower in potassium than bananas and oranges. These include apples, berries, grapes, pineapples, and pears.

Watermelon is generally classed as low to moderate in potassium, making it a suitable choice for people following a low-potassium diet. One standard serving of diced watermelon contains roughly 170 to 180 mg of potassium, which is far lower than levels found in fruits like cantaloupe.

According to the NHS, adults aged 19 to 64 need about 3,500 mg of potassium each day, which can usually be met through a balanced diet. A doctor can help address individual concerns and offer guidance based on personal health needs.
