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.

In today’s hyper-connected world, access to health information has never been easier. Yet, ironically, the ability to understand and apply that information remains one of the biggest barriers to better health outcomes.

This is where health literacy comes in, not just the ability to read a pamphlet or follow a doctor’s prescription, but the broader skill of accessing, comprehending, and using health information to make informed decisions for oneself, one’s family, and one’s community.

While definitions vary, there is consensus that health literacy is multi-dimensional. It involves confidence, critical thinking, and practical skills, knowing when to seek care, how to evaluate health claims, and how to follow treatment correctly. In essence, health literacy is the foundation of preventive care and treatment adherence, and its absence can be devastating.

The Challenge of Low Health Literacy in India

The scale of the problem in India is stark: nearly 90 percent of Indians have low health literacy. This gap directly affects patient outcomes, from delayed diagnoses and poor compliance with treatment to preventable complications and higher healthcare costs.

Several factors explain this reality:

• Low literacy levels: A significant proportion of the population cannot read or interpret basic medical instructions, leading to mismanagement of conditions.

• Poverty and affordability: For millions living on less than INR 100 a day, awareness alone is not enough when healthy choices remain unaffordable.

• Gender and cultural barriers: Women often have lower access to information and autonomy in health decisions, particularly around reproductive and maternal health.

• Distrust in healthcare systems: Overcrowded facilities and inconsistent care erode confidence, driving many to informal or unverified sources.

Low health literacy doesn’t just harm individuals; it amplifies inequities and strains the entire healthcare ecosystem. It also worsens misinformation, as people turn to social media or word-of-mouth for guidance, often encountering unverified or unsafe advice.

Blockbuster drug Ozempic, known for treating type 2 diabetes and obesity, has a surprising side effect. A new study published in The Lancet Psychiatry showed that the GLP-1 receptor agonists might prevent worsening of depression and anxiety.

People with diabetes or obesity are generally more likely than the general population to suffer from depression and anxiety. It is because both diabetes and obesity increase the risk of mental ill-health, and vice versa.

The findings showed that people with diabetes using semaglutide had a substantial decrease in hospitalizations and sick leave due to mental illness, including less worsening of depression, anxiety, and self-harm.

“Our findings suggest that GLP-1 drugs, particularly semaglutide, might contribute to better mental health in people with diabetes and obesity, but since this was an observational study, controlled clinical trials are needed to confirm the results,” said Jari Tiihonen, specialist physician and professor at the Centre for Psychiatry Research, Karolinska Institutet.

What Did The Study Find?

The research, led by an international team from Griffith University, the Karolinska Institutet, and the University of Eastern Finland, tracked Swedish national registers between 2009 and 2022.

It included 95,490 people, of which GLP-1 receptor agonists were used by 22,480 individuals during the follow-up period.

Semaglutide was associated with a decreased risk of worsening

• depression
• anxiety
• substance use disorder
• self-harm.

Patients using semaglutide experienced a 42 percent lower risk of hospitalization for mental health issues during periods of use, compared to periods when they were not taking the drug.

More specifically, the risk reduction was 44 per cent for sickness absence or hospital care due to depression, 38 per cent for anxiety disorders, and 47 per cent for substance use.

The team also found some benefits with Liraglutide. The drug was associated with an 18 per cent lower risk of sickness absence and hospital care due to psychiatric reasons.

How Does Semaglutide Work?

Semaglutide works as a GLP-1 receptor agonist that mimics the GLP-1 hormone to regulate appetite and blood sugar. It slows gastric emptying and makes you feel fuller longer. It also signals the brain to reduce hunger and cravings, and triggers the pancreas to release insulin when blood sugar is high.

They work by increasing insulin release in a glucose-dependent manner, decreasing the liver's production of glucagon, and slowing down the emptying of the stomach, which helps lower blood sugar levels after a meal. They also act on the brain to suppress appetite and increase feelings of fullness, leading to reduced calorie intake.

In people with type 2 diabetes, notes Harvard Health, the body's cells are resistant to the effects of insulin and the body does not produce enough insulin, or both. This is when GLP-1 agonists stimulate the pancreas to release insulin and suppress the release of another hormone called glucagon.

These drugs also act in the brain to reduce hunger and act on the stomach to delay emptying, so you feel full for a longer time. These effects can lead to weight loss, which can be an important part of managing diabetes.

In the wake of a young doctor from Chandigarh accusing a well-known private hospital of unnecessarily admitting patients to Intensive Care Units (ICUs), it is imperative to understand who truly requires critical care.

In a widely shared video posted on the social media platform Instagram, Dr Prabhleen Kaur alleged that the hospital is making the patients remain admitted in the ICU for as long as possible to mint money.

The doctor did not mention the name of the hospital. And HealthandMe could not independently verify the details and the authenticity of the post.

However, the incident reignited concerns over accountability, patient safety, and standards of care in the country.

Speaking to HealthandMe, Dr. Sachna Shetty, Consultant Emergency Medicine at Jaslok Hospital and Research Centre, said that: "ICU admissions are for patients with life-threatening conditions needing intensive support".

"This includes shock, respiratory failure, neurological emergencies, cardiac issues, and multi-organ dysfunction," the doctor added.

What Is ICU? Who Needs Critical Care?

The NHS UK explains that intensive care units (ICUs) are specialist hospital wards that provide treatment and monitoring for people who are very ill.

They're staffed with specially trained healthcare professionals and contain sophisticated monitoring equipment.

Also called critical care units (CCUs) or intensive therapy units (ITUs), it is required in cases where a person is seriously ill and requires intensive treatment and close monitoring.

Most people in an ICU have problems with one or more organs. For example, they may be unable to breathe on their own. Some common reasons include:

• a serious accident
• a serious short-term condition
• a serious infection
• a major surgery.

"ICU beds are limited, reserved for those who'll benefit most. Decisions are time-sensitive, based on triage and clinical scoring. It's about who needs advanced life support, not just who looks critical. Fair use of resources is key," the doctor added.

ICU Admissions: What India’s Guidelines Say

India’s ICU admission guidelines—issued by the Ministry of Health and Family Welfare in January 2024 — clearly defines who should and should not be admitted to an ICU. According to the guidelines:

• ICU admissions must be based on the severity of organ failure and the necessity for organ support or in anticipation of a potential deterioration in the patient's medical condition.
• Hospitals cannot admit critically ill patients in ICU in case of refusal by them and their relatives.
• ICU is not recommended in cases where there is no treatment possible or available, and if the continuation of therapy is not going to make an impact on the outcome, especially survival.
• Anyone with a living will or advanced directive against ICU care should not be admitted to ICU.
• Low priority criteria in case of a pandemic or disaster situation, where there is resource limitation, should be taken into account for keeping a patient in the ICU.
• Blood pressure, pulse rate, respiratory rate, breathing pattern, heart rate, oxygen saturation, urine output and neurological status among other parameters should be monitored in a patient awaiting an ICU bed

1. patients with altered level of consciousness,
2. hemodynamic instability,
3. need for respiratory support,
4. patients with acute illness requiring intensive monitoring
5. organ support or any medical condition or disease with anticipation of deterioration.

Guidelines For ICU Discharge Criteria In India

The guidelines stress the importance of physiological parameters returning to near-normal or baseline status.

Furthermore, reasonable resolution and stability of the acute illness that led to ICU admission are essential factors.

Patient and family agreement for ICU discharge, particularly in cases where a treatment-limiting decision or palliative care is opted for, is also highlighted.
