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.
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.
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.
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 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.
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 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.
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.
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.
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.

Aging is a significant factor in memory loss and cognitive decline. Now, a team of US researchers has pinpointed a single protein that drives these changes in the brains of the elderly.
In aging mice, higher levels of protein FTL1 weakened connections between brain cells, leading to memory decline.
But when FTL1 was reduced, the brain began to recover. It also rebuilt lost connections and restored memory performance, according to the study, published in Nature Aging.

"It is truly a reversal of impairments," said Saul Villeda, Associate Director at the University of California - San Francisco's Bakar Aging Research Institute and senior author of the paper. "It's much more than merely delaying or preventing symptoms."
While the research was carried out in aging mice, it holds immense potential for human brain function.
In the study, the researchers tracked shifts in genes and proteins in the hippocampus of mice. The FTL1 protein appeared consistently different between young and old animals.
Compared to young mice, the older mice showed higher levels of FTL1. They also had fewer connections between neurons in the hippocampus and performed worse on cognitive tests.
Increasing FTL1 levels in young mice produced brain changes similar to those seen in older mice. The researchers found that this change occurs because of alterations in the way nerve cells produce FTL1 protein.
In older mice, the nerve cells that produced high amounts of FTL1 developed simplified structures, forming short, single extensions instead of the complex, branching networks seen in healthy cells.
Further experiments showed that in older mice, higher levels of the protein slowed cellular metabolism in the hippocampus -- the part of the brain responsible for learning and memory.
However, when researchers treated these cells with a compound that boosts metabolism, the negative effects were prevented.

Villeda believes these findings could pave the way for treatments that target FTL1 and counter its effects in the brain.
"We're seeing more opportunities to alleviate the worst consequences of old age," he said. "It's a hopeful time to be working on the biology of aging."

Cancer treatment has long been thought to be unsuccessful among people of advanced age, and older adults are often left out of clinical decisions.
While they may face more surgical complications, a new study proved that even people aged over 80 can still safely have surgery and be cured. It showed that the overall health of a patient matters more and that age must not be the only criterion to rule out surgery.

The study, published in The Lancet Regional Health – Americas, showed that surgery for lung cancer is safe in elderly patients aged 80 and above, especially when the cancer is in an early stage.
Researchers at the Icahn School of Medicine at Mount Sinai and the Mount Sinai Tisch Cancer Center in the US found that they can recover like young cancer patients as well as live longer like them.
“As our population ages, more patients over 80 are being diagnosed with early-stage lung cancer, yet they are often not considered for surgery,” said Raja M. Flores, Chair of the Department of Thoracic Surgery at Mount Sinai Health System.
“Our findings show that when patients are carefully selected based on their overall health, not just their age, they can tolerate surgery well and experience excellent long-term outcomes,” he added.
The study findings are based on a study of 884 patients with early-stage lung cancer, including 114 people who were age 80 or older.
The researchers examined surgical outcomes and quality of life in patients with early-stage non-small cell lung cancer, comparing those aged 80 and older with younger patients.
The results showed that older patients lived just as long as younger patients after surgery. While some older patients had more complications right after surgery, most patients in both groups felt better over time, and their quality of life improved within a year.
The study noted that early detection in older patients may be key. The researchers called for screening guidelines to include patients who are over 80 years old based on these findings.

Lung Cancer is one of the most common and serious types of cancer. It is also the leading cause of cancer-related deaths worldwide, with approximately 2.5 million new cases and 1.8 million deaths reported in 2022.
According to the American Cancer Society, lung cancer mainly occurs in older people. Most people diagnosed with lung cancer are 65 or older; a very small number of people diagnosed are younger than 45.
The average age of people when diagnosed is about 70.
It is also the leading cause of cancer death in the US, accounting for about 1 in 5 of all cancer deaths.
In many cases, there are no symptoms; however, one must look out for these:

Cancer is not just a problem of elderly people anymore. In India, there has been an increased number of cases where individuals under the age of 40 are diagnosed with various forms of cancer. Even if there are fewer cases of this medical condition among younger people, this fact does not change the fact that one-fifth of all cancer patients in India are younger than 40 years.
Breast cancer, colorectal cancer, head and neck cancer, as well as blood cancer, are some types of cancer that become more common at a younger age. Among the most alarming statistics, the incidence of colorectal cancer in people aged 30-40 should be mentioned. Moreover, the fact that breast cancer becomes evident nine years earlier in Indian women in comparison with Western women must also be noted.
There is a wide variety of factors that contribute to this problem. These are the following:
Early detection saves lives. Some warning signs to look out for are:
Not only does it take time to diagnose cancer cases in young patients due to low suspicions, but these cancers also create an additional burden on people during their prime earning period.
There needs to be a paradigm shift in our understanding of this problem. First of all, we have to understand that cancer affects patients irrespective of their age, and therefore, when you experience some symptoms of cancer, do visit a doctor to get your condition checked out.
The key is maintaining healthy practices like balanced nutrition, exercising, not smoking, and limiting consumption of alcohol.
