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.

GLP-1 Microdosing: People Are Experimenting With Weight Loss Drugs & What Do Experts Have To Say About It?

Updated Jul 27, 2026 | 09:00 PM IST

SummaryAs the number of Ozempic, Wegovy, and Mounjaro users has increased significantly, the viral trend of GLP-1 microdosing has raised concerns.

As GLP-1 medications such as semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro, Zepbound) continue to help manage metabolic disorders and obesity, a new trend is rapidly gaining traction on social media - GLP-1 microdosing.

Instead of taking the prescribed doses approved for diabetes or obesity, some users are deliberately taking much smaller amounts, claiming they can lose weight, reduce food noise, avoid side effects, save money, or even improve longevity.

However, experts warn that there is currently little scientific evidence that GLP-1 microdosing is safe or even effective.

What Is GLP-1 Microdosing?

Some people reduce their dose by extending the time between injections, counting "clicks" on injection pens instead of using prescribed doses, or taking customized low-dose formulations.

HealthandMe spoke to Dr. Shehla Shaikh, Consultant Endocrinologist, Saifee Hospital, Mumbai, about the trend of GLP-1 microdosing.

Dr. Shaikh says, "The lowest dose that is supported by evidence for semaglutide is 0 25 mg. While, for tirzepatide, it is 2 5 mg Some people are using much smaller amounts for example using nine clicks on a semaglutide pen which gives about 0 06 mg. Now there are no randomized studies or clear guidelines that show if this kind of micro-dosing is safe or works."

Medical experts caution that these practices fall outside approved prescribing guidelines and have not been rigorously studied.

The expert says, "One big worry is how accurate the dose is. These injectable pens are made to give set approved amounts; not amounts based on people counting clicks. Even a small mistake in counting can mean taking too little medicine which may not work well or too much, which could cause more problems. Since these instructions are complicated, they need careful handling good eyesight and understanding of the device."

Why Are People Trying It?

Fewer Side Effects

Lower Cost

These medications are expensive in various countries. So, people stretch a single prescription by taking less medication than prescribed.

Weight Maintenance

Rather than pursuing significant weight loss, some users say they simply want to maintain previous results or reduce constant food cravings without taking full doses.

Longevity Claims

Online influencers have begun promoting low-dose GLP-1s as potential "longevity drugs." While GLP-1 medications show promise for heart and metabolic health, experts stress that these benefits have only been demonstrated using clinically tested doses, not microdoses.

The Risks of Microdosing

Reduced Effectiveness

Taking too little medication may fail to adequately suppress appetite, improve blood sugar levels, or achieve meaningful weight loss.

Dr. Shaikh says, "People often choose microdosing because they want to avoid problems reduce appetite with a smaller dose or make a costly medicine last longer. While smaller amounts might help a bit, current information shows that the best and steadiest results come from following the approved ways to take the medicine. Using doses that are too low might not give the results to people who want to lose weight or manage their metabolic health."

Delayed Medical Treatment Or Risk Of Expiration

Experts also say that people with obesity or diabetes could unknowingly receive suboptimal treatment while believing they are protected. Another problem is how long the medicine lasts after it is opened.

Dr. Shaikh explains, "An opened semaglutide pen should be used within 60 days while an opened tirzepatide pen should be used within 30 days. Because microdosing uses the medicine over a longer time, people might keep using it past the time it is safe which could change how good it is."

Inaccurate Dosing

Some users manually estimate doses by counting injection pen clicks. Experts warn these devices are designed to deliver specific calibrated doses, making partial dosing unreliable.

The expert says, "Some people think micro-dosing gives similar benefits with fewer problems or lower costs, but this practice has no scientific support and might have several dangers."

Doppler Test Explained: From Leg Pain to Pregnancy, When Do You Need One?

Updated Jul 27, 2026 | 04:12 PM IST

SummaryWhile commonly associated with pregnancy, Doppler ultrasound is also used to investigate conditions such as leg pain, swelling, varicose veins, blood clots, peripheral artery disease, and stroke risk.

A Doppler test is a specialized type of ultrasound that uses sound waves to measure blood flow through blood vessels rather than simply creating images of organs and tissues. Unlike a regular ultrasound, which produces pictures of internal structures, a Doppler ultrasound shows how blood moves through arteries and veins, helping doctors detect circulation problems.

While commonly associated with pregnancy, Doppler ultrasound is also used to investigate conditions such as leg pain, swelling, varicose veins, blood clots, peripheral artery disease, and stroke risk. Understanding when this test is needed can help detect serious conditions early and guide timely treatment.

Why Is Doppler Ultrasound Important During Pregnancy?

During pregnancy, a Doppler ultrasound is often recommended in high-risk cases to assess blood flow between the mother, placenta, and baby.

"It helps doctors monitor whether the fetus is receiving adequate oxygen and nutrients, making it especially important in pregnancies complicated by high blood pressure, diabetes, fetal growth restriction, or previous pregnancy-related complications," Dr. Vandana Mittal, Principal Consultant, Obstetrics and Gynecology, Paras Health Panchkula, told HealthandMe.

Dr. Vandana Jain, Principal Consultant - Obstetrics, Gynecology, Infertility & Advanced Laparoscopic Surgery, Yashoda Medicity, added that the test is commonly recommended in high-risk pregnancies, including fetal growth restriction, preeclampsia, hypertension, gestational diabetes, oligohydramnios, multiple pregnancies, and decreased fetal movements.

"By evaluating how effectively oxygen and nutrients are reaching the baby, the test helps detect signs of fetal compromise at an early stage, enabling timely monitoring, appropriate medical intervention, and informed decisions regarding the timing and mode of delivery."

By identifying potential issues early, Doppler studies help doctors monitor pregnancies more closely and intervene when necessary. However, the test is performed only for specific medical indications and is not a replacement for routine pregnancy ultrasounds.

What Other Conditions Can a Doppler Ultrasound Detect?

According to the Mayo Clinic, a Doppler ultrasound can help diagnose:

  • Blood clots
  • Venous insufficiency, where poorly functioning vein valves cause blood or fluid to pool in the legs
  • Heart valve defects and congenital heart disease
  • Arterial occlusion (blocked arteries)
  • Peripheral artery disease
  • Aneurysms
  • Carotid artery stenosis, which increases stroke risk

How Doppler Ultrasound Can Help People With Leg Pain

Dr. Jain said Doppler ultrasound is also commonly advised for patients with suspected Deep Vein Thrombosis (DVT), peripheral arterial disease, carotid artery narrowing, or chronic venous insufficiency.

"It is commonly advised for patients with suspected Deep Vein Thrombosis (DVT), peripheral arterial disease, carotid artery narrowing, or chronic venous insufficiency," she told HealthandMe.

The expert added that people with persistent leg pain while walking, unexplained swelling, non-healing wounds, or symptoms of poor circulation may require a Doppler evaluation.

Recently, gastroenterologist Dr. Pal Manickam highlighted the importance of Doppler ultrasound during a podcast discussion. He urged people not to ignore sudden leg pain or swelling, noting that these symptoms could indicate deep vein thrombosis (DVT) and require prompt evaluation.

How Is a Doppler Test Done?

The procedure is painless, non-invasive, and usually takes 30 to 60 minutes, depending on the area being examined. It is also radiation-free.

A Doppler ultrasound is performed by a trained sonographer using a hand-held device called a transducer. The transducer sends sound waves into the body and measures how they bounce off moving blood cells, allowing the machine to assess blood flow in real time.

Prostate Cancer: NHS England's New Precision Radiotherapy Offers Hope In Just 5 Sessions

Updated Jul 27, 2026 | 05:00 PM IST

SummaryAccording to NHS England, stereotactic ablative radiotherapy (SABR) delivers highly targeted radiation to the tumor from multiple angles, helping reduce the risk of the cancer returning or spreading.

A new high-precision radiotherapy treatment introduced by NHS England is set to offer a faster and more convenient treatment option for thousands of men with prostate cancer.

Known as stereotactic ablative radiotherapy (SABR), the treatment delivers high-dose radiation in just five sessions over two weeks, compared with the 20 or more sessions typically required with conventional radiotherapy. This means eligible patients can complete treatment with 15 fewer hospital visits, reducing the burden of travel and time spent in care.

Prostate cancer is the most common cancer among men in the UK. More than 55,000 men are diagnosed with the disease each year, while around 12,300 die from it annually.

According to NHS Chief Executive Sir Jim Mackey, the new therapy will "transform" treatment for thousands of men with localized prostate cancer while enabling the NHS to provide "far more powerful and more convenient" cancer care.

How Does SABR Work?

According to NHS England, stereotactic ablative radiotherapy (SABR) delivers highly targeted radiation to the tumor from multiple angles, helping reduce the risk of the cancer returning or spreading.

The treatment delivers a higher dose of radiation with pinpoint accuracy, minimizing damage to surrounding healthy tissue and reducing the likelihood of side effects.

"This technology lets us focus a powerful and precise beam of radiotherapy directly onto the cancer, limiting the damage to healthy cells – and the fact it can be delivered in 15 fewer doses will help men get back to living their lives far more quickly," said Professor Peter Johnson, NHS National Clinical Director for Cancer.

Also known as stereotactic body radiotherapy (SBRT), SABR is already used to treat certain lung and brain cancers. It is now being offered on the NHS to eligible men with low- and intermediate-risk localized prostate cancer.

Who Can Benefit?

Around 17,500 men in England are diagnosed with low- or intermediate-risk prostate cancer each year and could be eligible for SABR.

NHS modeling suggests that nearly one in five of these patients—around 3,500 men annually—may choose the treatment to help reduce the risk of their cancer spreading.

The treatment is expected to be available across all 48 NHS radiotherapy centers in England, with the first hospitals beginning to offer it from next week.

Could Reduce Waiting Times

The NHS estimates that introducing SABR for prostate cancer could free up around 50,000 treatment appointments each year.

By shortening treatment schedules and reducing the number of hospital visits, the rollout is expected to improve capacity across radiotherapy services while helping bring down waiting times for cancer patients.

However, SABR is not suitable for everyone with localized prostate cancer. Experts advise patients to discuss their treatment options with their specialist team, while ongoing research continues to evaluate the therapy in different patient groups.

The prostate is a small, walnut-shaped gland in men that produces seminal fluid, which nourishes and transports sperm. Prostate cancer develops when abnormal cells begin to grow uncontrollably in the gland.

Experts say not all prostate cancers are life-threatening. Many are slow-growing and may never affect a man's lifespan. In fact, such cancers are found in around one in three men over the age of 50. However, a smaller number of prostate cancers are aggressive, spread quickly, and require prompt treatment, making early detection and regular screening important.

Symptoms of Prostate Cancer

Early-stage prostate cancer may cause:

  • Blood in the urine or semen
  • Difficulty urinating
  • Erectile dysfunction

More advanced prostate cancer may lead to:

  • Decreased force of the urine stream
  • Bone pain
  • Unexplained weight loss.
