Metabolism plays a big role in our health, it’s not just about helping your digestive system work smoothly, but the way your body breaks down the food and helps nutrients get absorbed into the body that matters. But often due to one reason or the other, your metabolism can slow down, which then causes issues with people. Many people think that the reason they may be gaining weight could be because of their poor metabolism, so how does one go about fixing this issue and how do you even know that the fault lies with your metabolism.

To understand why your metabolism may be slowing down, we must understand what role it exactly plays. Metabolism is the process your body uses to turn food into energy. It's essential for everything from breathing and digestion to keeping you warm. Several things affect how fast your metabolism works, including your genes, health, and lifestyle. A slow metabolism means your body burns fewer calories, which can lead to tiredness, dry skin, weight gain, and cravings.

Why Does Your Metabolism Slow Down?

There can be many reasons why your metabolism may be slowing down. You inherit some of it, and it tends to slow down as you age, often due to changes in your body and less muscle. Men and women have different metabolisms because of body size, makeup, and hormones. What you eat matters too – not enough healthy food or a very low-calorie or high-fat diet can slow it down. A lazy lifestyle, lack of sleep, and stress can also make your metabolism sluggish. Certain health problems like diabetes or an underactive thyroid, and even environmental factors, may also play a role.

Signs You Need To Improve Your Metabolism

While these are some common signs, it is best to visit a healthcare professional and ask for their opinions before you try a solution. There are many underlying reasons as to why you are experiencing slow metabolism, it can also be a side-effect of some medicine. A healthy lifestyle goes a long way, especially for people who already have digestive issues, kidney or even mental health issues like stress and anxiety.

Constant Fatigue

Feeling tired all the time, even without a good reason, could mean your metabolism is slow. A slow metabolism means your body breaks down food into energy slowly, leaving you with low energy levels. You might feel sluggish or get tired easily throughout the day. Changes in what you eat or your body composition (how much fat and muscle you have) can also make you feel more tired.

Dry Skin

Dry skin is common in winter, but if you have it all the time, it could be a sign of a slow metabolism. Thyroid hormones help control your metabolism and also keep your skin hydrated. If your thyroid isn't working right and your metabolism is slow, your skin might get very dry.

Weight Gain

If you're eating healthy and exercising but still gaining weight, a slow metabolism could be the problem. A slow metabolism doesn't turn food into energy quickly, so you burn fewer calories. Extra calories are stored as fat, making it hard to lose weight.

Feeling Cold

Feeling cold even when it's not cold outside can be a sign of a slow metabolism. Your body generates heat through metabolism. If your metabolism is slow, your body temperature might be lower. Some studies show that people with an underactive thyroid or obesity may have lower body temperatures because of a slow metabolism. This can be because of problems with thyroid hormones, which help your body make heat.

Food Cravings

Craving sugary or fatty foods can be a sign of a slow metabolism. Studies show that cravings are related to metabolic health. This is especially true for people who don't eat enough healthy foods, have bad eating habits, or have low muscle mass and high fat mass. Cravings might also mean your body isn't getting enough energy from the food you eat, so it wants more energy.

Mood Swings

Everyone has mood swings sometimes. But if you have them often, it could be from a slow metabolism. Low energy and hormone problems that come with a slow metabolism can make you irritable and frustrated. Some older research also suggests a link between mental health issues and a slow metabolism.

Digestive Problems

Digestion and metabolism are connected. Digestion breaks down food, and metabolism turns it into energy. If your metabolism changes, like slowing down, it can affect your digestion. A slow metabolism can cause constipation, bloating, or diarrhea.

According to a recent study, the rate of strokes among young adults in the United States has nearly doubled in the last two decades. With risk factors like high blood pressure, diabetes and high cholesterol surfacing years earlier, experts are seeing an increasing number of stroke emergencies under the age 40.

On World Stroke Day, Dr Arup Sen, London-based physician, specialising in geriatric, stroke and General Medicine and affiliated with Cleveland Clinic London, National Hospital for Neurology and Neurosurgery, and University College Hospital, spoke to HealthandMe about the alarming pattern of stroke rates among young people.

The doctor said that recreational drug use, smoking, sedentary behaviour and obesity add to stroke risk, while certain underlying medical conditions could also be triggers.

Dr. Sen said, “The bottom line is that what we refer to as stroke risk factors, the risk factors are arriving decades earlier compared to previously. And that's why we're seeing this surge in stroke rates in young people.”

Recreational Drugs And Steroid Use Fuel Stroke Risk

Dr Sen said recreational drugs affect blood vessels and blood pressure directly, increasing the risk of stroke. Cocaine, for instance, can narrow the blood vessels that could disrupt blood flow to the brain. It can also trigger sudden increases in blood pressure.

“Generally speaking, most substances cause stroke through a mechanism of causing vasospasm and a surge in blood pressure or high blood pressure, which then increases the risk of having a stroke,” he said.

Cannabis use has also been linked to risk of stroke according to some studies. Dr Sen referred to research reporting an association between cannabis use and stroke, including studies examining daily use. He noted that tobacco use can complicate the picture because some people smoke cannabis with tobacco.

“Tobacco itself is a risk factor for stroke. So, for example, people who smoke cigarettes have twice the risk of stroke as someone who doesn't smoke,” he said.

He also warned against combining smoking with vaping, saying that research has associated dual use with a higher stroke risk.

The doctor said that anabolic steroids used for bodybuilding is a major concern. According to Dr Sen, these substances can lead to thickening of the blood which inceases blood clotting risk and affect the structure of the heart. This could lead to abnormal heart rhythms and blood clots.

“One of the most important ways in which you can increase risk is it can make the blood more thick and sticky, increasing risk of blood clots, but it can also affect the heart in terms of causing what we call a cardiomyopathy,” he said.

His advice to people using anabolic steroids for bodybuilding was straightforward. He said, “Don't use them, just avoid them altogether, because if you're using it, there's going to be a risk.”

Birth Control And Migraine With Aura Fuel Stroke A Risk In Young Women

Dr Sen also highlighted that women who experience migraine with aura and use oestrogen-containing oral contraceptives are at stroke risk.

Migraine with aura involves neurological symptoms that can occur before or during a migraine attack. According to Dr Sen, the oestrogen component of certain contraceptives can increase the risk of blood clots and stroke in women with this history.

He said, “If a young lady with a history of migraine and aura has a stroke, then we would recommend them, and they're using contraceptives, we would recommend them using progesterone-only contraceptives, avoiding oestrogen, because the oestrogen component is a risk factor for strokes.”

The choice of contraception, however, should be always discussed with a healthcare professional.

Hidden Causes Of Stroke In Younger Adults

Not every stroke in a younger person is explained by conventional risk factors. Dr Sen said doctors investigate conditions that may be more relevant in younger patients, including patent foramen ovale (PFO), antiphospholipid syndrome (APS) and arterial dissection.

A PFO is an opening between the upper chambers of the heart. Dr Sen explained that even though it is common, occurring in around one in four people, in certain cases it can allow a blood clot to pass through the heart and travel to the brain.

Antiphospholipid syndrome is a condition that can increase the tendency to form blood clots. Arterial dissection, meanwhile, involves a tear in the wall of an artery. Dr Sen said it can occur in association with sports or neck manipulation and may initially cause neck pain or headaches before neurological symptoms develop.

He said PFO and arterial dissection were the two most common unusual causes he had encountered in younger stroke patients, followed by antiphospholipid syndrome.

He said, “The most common cause I've seen is PFO, definitely, followed by dissection, and then probably antiphospholipid syndrome.”

Stroke Symptoms In Young People Can Be Overlooked

Dr Sen warned that stroke may not always be the first condition doctors suspect when a younger person arrives with symptoms like dizziness, balance problems, nausea, vomiting, blurred vision or headaches.

Posterior circulation strokes, which affect the back of the brain, can cause symptoms that resemble other conditions. These may be mistaken for intoxication, gastroenteritis or migraine, potentially delaying diagnosis.

“There's this common myth that stroke, if it happens, it's inevitable. There's nothing you could have done to prevent it. But the opposite is true, because the majority of strokes are actually preventable if you address the risk factors in a proactive fashion,” he said.

How Can Younger Adults Reduce Their Stroke Risk?

Dr Sen urgently recommends addressing lifestyle factors, keeping key health biomarkers in check and recognising stroke symptoms at the earliest.

He advised younger adults to stay physically active, avoid smoking and recreational drugs, maintain a healthy diet, get adequate sleep and avoid binge drinking. He also urged people to monitor their blood pressure, cholesterol and blood glucose rather than assuming these checks are necessary only later in life.

He said, “Know your numbers. By that, I mean, your risk factors. Even in as early as your mid 20s to early 30s, you should be looking at your blood pressure, cholesterol and diabetes markers.

Dr Sen also said that some people may have genetically elevated cholesterol even when they are young. He also mentioned lipoprotein(a), or Lp(a), a largely genetically determined risk factor that is not routinely included in every standard cholesterol assessment.

Finally, he stressed the importance of recognising the signs of stroke through the BEFAST acronym:

• B – Balance: Sudden loss of balance or coordination.
• E – Eyes: Sudden vision loss or double vision.
• F – Face: Drooping on one side of the face.
• A – Arms: Weakness or one arm drifting down.
• S – Speech: Slurred speech or difficulty finding words.
• T – Time: Call emergency services immediately.

“The mantra in stroke that we use is time is brain,” Dr Sen said. “The earlier you get to the hospital and see the specialists and get the right treatment at the right time and the right place, the better the outcomes.”

People with hemophilia face an increased risk of poor bone health due to recurrent joint and muscle bleeds, joint damage and reduced physical activity. Experts told HealthandMe that preventing bleeds from childhood, alongside adequate nutrition, appropriate exercise and regular assessment, can help protect bone health throughout life.

Globally, an estimated 836,000 people have hemophilia, including approximately 284,000 with severe hemophilia. In India, the World Federation of Hemophilia (WFH) reported nearly 28,000 diagnosed and registered patients as of 2026, including more than 24,000 with Hemophilia A. However, the estimated prevalence could be as high as 1,36,000, suggesting many cases remain undiagnosed or misdiagnosed.

Childhood and adolescence are critical for building peak bone mass, making early intervention important for long-term musculoskeletal health, said health experts.

How Hemophilia Can Affect Bone Health

Hemophilia is an inherited bleeding disorder caused by a deficiency of clotting factor VIII (Hemophilia A) or factor IX (Hemophilia B). It primarily affects males, while women are often carriers.

Repeated bleeding into joints can cause chronic pain, joint damage, deformity and reduced mobility. Muscle bleeds can further restrict movement, limiting participation in physical activities that help maintain bone strength.

“Bone health begins in childhood, but protecting it is a lifelong commitment. In people living with hemophilia, recurrent joint and muscle bleeds, reduced physical activity and other risk factors can contribute to poor bone health and an increased risk of osteoporosis,” Dr. Varun Bafna, associate professor in the Department of Hematology at Chhatrapati Shahu Maharaj Government Medical College, Kolhapur, told HealthandMe.

Why Prophylaxis Matters

Prophylaxis involves preventive treatment to reduce bleeding episodes rather than treating bleeds only after they occur. Regular factor prophylaxis can help prevent recurrent joint bleeds, preserve joint function and support mobility.

“Regular factor prophylaxis helps prevent repeated joint bleeds and preserve joint function. That protection can support mobility, an important contributor to bone health,” Dr. Hitha B, associate professor and haematologist in the Department of Medicine at Government Medical College, Kozhikode, told HealthandMe.

She advised patients to discuss breakthrough bleeding or difficulties accessing treatment with their healthcare team so their treatment plan can be reviewed.

Dr. Bafna said consistent prophylaxis can also support muscle strength and safer participation in physical activity.

“Prophylaxis is not just about preventing bleeding today; it is an important part of protecting long-term musculoskeletal health and quality of life at every age,” he noted.

How to Protect Bone Health From Childhood

Experts recommend an individualized approach based on age, joint health, mobility and other risk factors. Key measures include:

• Calcium and vitamin D: Ensure adequate intake through diet and discuss supplementation with a healthcare professional when needed.
• Appropriate physical activity: Weight-bearing exercises suited to individual joint health can help maintain bone strength, with guidance from the care team.
• Physiotherapy: Tailored rehabilitation can help maintain muscle strength, mobility and joint function.
• Regular assessment: Periodic evaluation can identify bone-health concerns and determine whether further investigations are needed.
• Consistent prophylaxis: Adhering to prescribed preventive treatment can reduce bleeding episodes and help protect joints.

A Multidisciplinary Approach to Lifelong Care

Hematologists, physiotherapists and other healthcare professionals can help patients and families integrate preventive treatment, rehabilitation, nutrition and appropriate physical activity into an individualized care plan.

Early intervention and consistent care can help preserve joint function, mobility and quality of life as people with hemophilia grow older.

A stroke rarely announces itself loudly. A sudden wobble, a blurry eye or a slightly lopsided smile is easy to ignore. But in a stroke, minutes decide how much of the brain survives.

On World Stroke Day, doctors want everyone to know one simple tool: BE FAST.

What Doctors Say

Dr. Abhinav Gupta, Director of Neurology at Sarvodaya Hospital, Greater Noida West, and Dr. Atampreet Singh, Senior Director and Head of the Institute of Neurosciences at ShardaCare, Healthcity, told HealthandMe, “Knowing the early warning signs of a stroke can shorten the road to full recovery,” they said.

The problem, they added, is that “a stroke’s symptoms can be easy to dismiss as minor inconveniences, like being tired or having weak muscles.”

What Is BE FAST?

BE FAST was developed by Intermountain Healthcare as an adaptation of the American Stroke Association’s FAST model, according to a Frederick Health handout. The doctors break it down like this:

• B – Balance: “Unsteady feeling or sudden lack of muscle control and dizziness can be a warning sign of a stroke.”
• E – Eyes: “Don’t overlook loss of sight in one or both of a person’s eyes, sudden blurring, or double vision.”
• F – Face: “Ask the person to smile. Unevenness or droopiness on one side of the face can be a sign.”
• A – Arms: “Have the person raise both of their arms. If the person has difficulty holding one arm up or has unusual arm weakness, get emergency help.”
• S – Speech: “Sudden lack of ability to talk, inability to understand what others are saying, or slurred words, can be signs of a stroke.”
• T – Time: “If one of these symptoms occur out of the blue, then call emergency services. When the emergency operators are on the line, let them know what symptoms have presented.”

Why “Time” Matters The Most

Time is not a symptom. It is a reminder to hurry. Duke Health, citing the American Stroke Association, says to call for help even if the symptoms go away. Weill Cornell Medicine, citing the same group, says never to drive yourself to hospital.

The Frederick Health handout adds that you should note when the symptoms began. UChicago Medicine estimates that about 1.9 million brain cells die every minute in a stroke caused by a large blocked artery.

India’s biggest problem is delay in seeking medical treatment.

An ICMR study of 34,792 stroke cases at 30 hospitals between 2020 and 2022 found that only 5.3% of patients reached hospital within the first hour, according to South First. Nearly four in ten waited more than 24 hours. Down To Earth, reporting on a Lancet Neurology study, says India had over 1.25 million new stroke cases in 2021, up 51% since 1990.

If you see even one sign, don’t wait for the others. Call 112, India’s single emergency number, which also covers the 108 ambulance service, according to Factly. Say what you see and when it began.
