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.

It was during the COVID-19 pandemic that Annabelle Gurwitch, an American author, actress, and television host, developed a "a little persistent cough".

Suspecting it to be a COVID symptom, Annabelle went for a check-up. Her doctor alarmingly informed her about something suspicious on her lungs. Soon after, an X-ray and a biopsy confirmed her diagnosis of stage 4 cancer.

But, here's the catch. Annabelle is a non-smoker. She also lived a healthy lifestyle and exercised every day, and felt like she was in really good health, besides the persistent little cough.

HealthandMe spoke to health experts to understand how a persistent cough signals the risk of lung cancer.

If you, too, are a non-smoker who is leading a healthy lifestyle and has no medical conditions other than a persistent cough, then you must visit your doctor right away, advised the experts.

"A persistent cough can be an early warning sign of lung cancer, especially when it shows specific features rather than behaving like a routine respiratory illness," Dr Sameer Khatri, Principal Director - Medical Oncology, Max Super Speciality Hospital, Patparganj, told HealthandMe.

The doctor noted that the cough becomes suspicious when it persists beyond three weeks without a clear cause or fails to respond to standard symptomatic treatment such as cough syrups, bronchodilators, etc.

"A change in a pre-existing smoker’s cough—for example, becoming more frequent, severe, or different in character—is particularly important. In non-smokers, a new, unexplained chronic cough should not be ignored," Dr. Khatri said.

Certain associated symptoms further strengthen the suspicion of cancer. The most significant is hemoptysis, the coughing up of blood or blood-stained mucus, even if minimal.

Other red flags include

• unintentional weight loss,
• chest pain,
• breathlessness,
• hoarseness,
• recurrent pneumonia in the same lung region.
• age >40 years,
• smoking history, occupational exposures.

Persistent cough: TB Vs Lung Cancer

Persistent cough also signals the risk of tuberculosis (TB) -- the world's most deadliest infectious disease. Understanding the differences between these two causes is critical for early diagnosis and timely treatment.

Dr Seema Jagiasi from MOC Cancer Care Center told HealthandMe that the cough in TB may sometimes produce blood-tinged phlegm, but it is usually associated with signs of infection, such as fatigue and a general feeling of illness.

TB is more common in younger populations and in individuals with weakened immunity or poor living conditions.

"In contrast, a cough associated with lung cancer tends to be more insidious. It may start as a dry, persistent cough that gradually worsens over time. Unlike TB, it may not initially present with fever or infection-related symptoms," the doctor explained.

One of the key differences lies in progression and response to treatment.

TB is treatable with a course of antibiotics, and symptoms often improve within weeks of starting therapy. However, a lung cancer-related cough persists or worsens despite routine medications.

Dr Jagiasi emphasized that any cough lasting beyond three weeks, especially when accompanied by alarming symptoms, should not be ignored.

"Early investigations, such as chest imaging and further diagnostic tests, can help distinguish between the two conditions," the doctor said.

While both TB and lung cancer may present with a persistent cough, their underlying causes, associated symptoms, and progression differ significantly.

The health experts called for more awareness and the need for timely medical evaluation for the effective management of the disease.

Irish Actor Michael Patrick, known for his significant role in Game of Thrones, has sadly passed away at the young age of 35.

Sharing the news in a post on social media platform Instagram, his wife Naomi Sheehan shared that Michael Patrick (whom she fondly calls Mick) died after a years-long battle with Motor Neurone Disease.

"Last night, Mick sadly passed away in the Northern Ireland Hospice. He was diagnosed with Motor Neurone Disease on 1st February 2023. He was admitted 10 days ago and was cared for by the incredible team there. He passed peacefully, surrounded by family and friends," Naomi said.

Calling Michael a "titan of a ginger-haired man", she said that “Words can’t describe how broken-hearted we are".

Naomi called Michael an "inspiration to everyone."

What Is Motor Neurone Disease (MND)

MND is a rare and progressive neurodegenerative disease. According to NHS UK, it causes muscle weakness that gets worse over a few months or years. It's usually life-shortening, and there's currently no cure, but treatment can help manage the symptoms.

Symptoms of MND include:

• stiff or weak hands
• weak legs and feet
• twitches, spasms, or muscle cramps (where muscles painfully tighten).

It makes everyday tasks such as climbing stairs or gripping objects difficult.

As the disease advances, patients may develop difficulties with breathing, swallowing, and speech, along with changes in mood or personality. In later stages, walking and movement can become extremely limited.

Treatment of MND

About 1,500 people are diagnosed with MND each year, yet treatment choices remain scarce. Only a small proportion of patients currently qualify for therapies that target the disease process itself.

MND can be difficult to diagnose in the early stages. But as the symptoms get worse, it can usually be confirmed.

Tests used to help diagnose MND include:

• blood tests
• tests to check how well your nerves are working
• an MRI scan to help rule out other conditions that affect the brain and nerves

1. Amyotrophic lateral sclerosis (ALS): Early symptoms include muscle weakness in the arms and legs can cause you to trip and drop things.

2. Progressive bulbar palsy (PBP): It mainly affects muscles in the face, throat, and tongue, causing slurred speech and problems swallowing.

3. Progressive muscular atrophy (PMA): It causes weakness in the hands.

4. Primary lateral sclerosis (PLS): Leads to weak legs, sometimes with other symptoms, including speech problems.

Common treatment options for MND include:

• physiotherapy and exercises to help with muscle weakness and stiffness
• dietary advice to help you maintain weight
• speech and language therapist to help with talking
• Cognitive behavioral therapy (CBT) to help cope with emotions and feelings, such as anxiety and depression.

During the COVID-19 pandemic, the SARS-CoV-2 virus had a significant impact on the eyes, causing conjunctivitis (pink eye), with red, itchy, watery, or painful eyes.

A new study now shows that eye symptoms may also be key in understanding the severity of long COVID, a collection of symptoms that last three months or longer after your first COVID symptoms.

The new study, published in the journal Clinical Ophthalmology, showed that the new onset of eye symptoms in people with long COVID may be an indicator of more severe disease.

Key Findings

Researchers from the Yale School of Medicine analyzed survey data from 595 adults who self-reported having long COVID in surveys conducted from May 2022 to October 2023. They found that nearly 60 percent of people reported new-onset of ocular symptoms.

The findings suggest that ocular symptoms in long COVID may be interpreted as vision-related manifestations that cluster with systemic post-COVID conditions. The symptoms include a new onset of :

• blurred or lost vision,
• dry eyes,
• floaters or flashes

Notably, individuals with ocular symptoms reported:

• A greater overall symptom burden,
• Financial difficulties,
• Challenges in everyday life.

What is Long COVID

Long COVID includes a wide range of symptoms or conditions that may improve, worsen, or be ongoing. While anyone who gets COVID-19 can develop Long COVID, studies have shown that some groups of people are more likely to develop Long COVID than others, including:

• Women
• People who have experienced more severe COVID-19 illness, especially those who were hospitalized or needed intensive care
• People with underlying health conditions
• People who did not get a COVID-19 vaccine

While many of the Long COVID conditions remain to be fully recognized, some people have more than one symptom that can be moderate to severe, and also impact the quality of life. According to the US CDC, they include:

• Tiredness or fatigue
• Difficulty thinking or concentrating (sometimes called “brain fog”)
• Shortness of breath or difficulty breathing
• Headache
• Dizziness on standing
• Fast-beating or pounding heart (known as heart palpitations)
• Chest pain
• Cough
• Joint or muscle pain
• Depression or anxiety
• Fever
• Loss of taste or smell
