Do you have these symptoms too? Maybe this is Pellagra!

Do you sometimes feel like you have no energy, are you constantly having stomach problems, sometimes with diarrhea? Not only that, but do you also have skin problems, strange symptoms, etc.? These can actually be symptoms of different diseases. However, today we are going to talk about a slightly different condition that sometimes comes together. That is a disease called pellagra .

What is Pellagra?

Simply put, Pellagra is a disease caused by a deficiency of a vitamin called niacin , also known as vitamin B3 . This is also a type of malnutrition. Specifically, it is a micronutrient deficiency. Niacin is essential for the functioning of the cells in our body. So when it is low, its effects are manifested as symptoms throughout our body, especially in places like the skin, mouth, intestines, and brain. If not treated properly, Pellagra can cause permanent damage to the nervous system and sometimes even death. Now you may be wondering if everyone gets this. Most of the time, a person who eats a balanced diet gets the required amount of niacin. However, primary pellagra – which is caused by a lack of niacin in the diet – is still a major problem in poor, food-deprived areas. However, in developed countries, like Sri Lanka, niacin deficiency is often secondary to other causes. That is, other disease states or substances that prevent our bodies from absorbing or using niacin properly.

What is Niacin? Why do we need it?

Our bodies use niacin to convert the calories in the food we eat into energy. Think of the food we eat as the gasoline that powers our car. For that gasoline to run, it needs to be properly refined. That's what niacin does. The niacin we get from the food we eat is absorbed into our body's tissues through our small intestine. There, it becomes a coenzyme called Nicotinamide Adenine Dinucleotide (NAD) . This NAD helps more than 400 enzymes in our body function. Simply put, this NAD is the main thing that helps our body's cells make energy (also called Adenosine Triphosphate (ATP) ). Additionally, NAD contributes to many important functions, such as DNA repair and communication between cells.

How does niacin deficiency affect my body?

Because NAD is a key factor in providing energy to cells, when it is depleted, it first affects the systems that need the most energy or are dividing rapidly. That means your skin, the lining of your gastrointestinal tract (from your mouth to your intestines), and your brain. Doctors call the main symptoms of pellagra the "3 Ds":Diarrhea, dermatitis, and dementia. Some even add a fourth "D": death . If left untreated for years, death can result.

1. Diarrhea (Gastrointestinal mucositis)

Diarrhea occurs when the lining of your intestines (mucosa) doesn't regenerate properly. Think of it like a protective coating on the inside of your intestines. When it's gone, your intestines can't properly digest food or protect themselves from infection or injury. This can lead to ongoing inflammation from your mouth to your intestines. This can result in symptoms like stomach pain, indigestion, mouth sores, and a red, swollen tongue .

2. Dermatitis (Skin photosensitivity)

Pellagra is a specific type of skin disease that affects the skin, especially the face, neck, arms, legs, palms, and soles of the feet, which are exposed to the sun . When the cells lose their energy, the skin cells become very sensitive to sunlight. At first, the skin turns red and looks like it has been sunburned. Later, the areas become rough, scaly, and sometimes black (hyper-pigmented) plaques may appear. One of the hallmarks of this disease is a dark band around the neck. It is called "Casal's collar." This is named after the doctor Don Gaspar Casal, who first identified the disease among Spanish peasants in 1735.

3. Dementia (Brain and nerve damage)

Pellagra is a disease that affects the entire body. Because every cell in the body loses the energy it needs to do its job, it eventually affects the brain and nervous system. Early symptoms may not be very obvious. You may just feel lethargic, apathetic, and have difficulty concentrating . Or you may experience symptoms such as anxiety and depression . Over time, these symptoms can progress to confusion and delusions . In severe cases, permanent dementia can occur, as well as neurological problems such as difficulty with balance and walking, muscle twitching, and tremors .

Where is Pellagra most commonly seen?

Historically, pellagra has been found in poor people all over the world, in countries like Europe, Africa, Asia, and South America. It has often been seen in people with very limited food intake. Especially in those who were low in protein and had a diet based on corn. This is because niacin requires protein and amino acids to be properly absorbed by the body. Although corn contains niacin, it is in a "bound" form that our bodies cannot easily absorb.

In Central and South America, traditionallyWhen making tortillas from corn , the corn is soaked overnight in lime water. This process releases the niacin in the corn and makes it more absorbable. That is why pellagra is very rare in those regions.

Nowadays, Pellagra is very rare in developed Western countries like America. This is due to the fortification of bread and rice with niacin. However, primary Pellagra is still seen in less developed regions of the world, especially among tribal peoples who eat maize as their staple food. This condition still exists in India, China, and some parts of Africa. Although primary Pellagra is rare in countries like Sri Lanka, we should be concerned about Pellagra caused by secondary causes .

What are the symptoms of Pellagra?

Here are some common symptoms of pellagra:

• Persistent diarrhea , sometimes with blood.
• Stomach pain and indigestion .
• Loss of appetite , nausea , and vomiting .
• Eczema rash with itching or pain on the skin .
• Mouth sores and a red, swollen tongue.
• Extreme fatigue, weakness, and lethargy.
• Mood swings, depression.
• Nervous system symptoms - for example, tremors and numbness in the limbs.
• Delirium and dementia.

What are the causes of Pellagra?

The main cause is a diet low in niacin. We get vitamin B3 (niacin) from a variety of foods. However, people with limited food choices may be deficient in some nutrients. Pellagra can also develop due to secondary causes . That is, other health conditions that prevent your body from absorbing or using niacin properly. Some examples are:

• Gastrointestinal diseases that cause malabsorption - for example , Inflammatory Bowel Disease (IBD) orCirrhosis of the liver.
• Alcohol use disorder: Excessive alcohol consumption can damage organs like the liver and reduce the body's ability to absorb nutrients like niacin. This can lead to malnutrition.
• Gastric bypass surgery: After some surgeries for obesity, the intestinal mucosa can be damaged, leading to various micronutrient deficiencies, including niacin.
• Iron deficiency anemia: The body also needs iron to convert and use niacin.
• Hartnup disease: This is a genetic disease. It prevents the body from absorbing amino acids. These amino acids are essential for making vitamins.
• Carcinoid syndrome: In this, the production of niacin by cancer cells is reduced.
• Certain medications: Some medications, especially antispasmodics and chemotherapy drugs, can interfere with niacin metabolism.
• HIV infection: HIV infection causes a decrease in niacin levels in the body.

How is Pellagra diagnosed?

When you see a doctor, he or she will examine you and ask about your symptoms, your medical history, and your diet. If pellagra is suspected, a urine test may be done to confirm the diagnosis. The levels of certain chemicals in your urine can tell you whether you have enough niacin in your body. Your doctor may also give you niacin supplements to see if they help. That is one way to diagnose the disease.

What are the treatments for Pellagra?

Pellagra is caused by a deficiency of niacin, or vitamin B3. So, the best treatment for it is to replenish the body with the missing nutrient. That means giving niacin supplements. Most people start to recover quickly once they start taking these. However, additional treatment may be needed for things like skin lesions and mouth ulcers.

The most important thing is that if you have pellagra due to a secondary cause, that is, another disease, then you need to properly treat that underlying disease as well.

Are there any side effects to the treatment?

If you take the medicine as prescribed by your doctor, niacin supplements usually do not cause any major side effects. However, if you overdose, some side effects may occur. However, someone with a deficiency in their body will not easily overdose. If that happens, the following things can happen:

• Skin flushing.
• Itching and eczema rashes.
• Bloating and indigestion.
• Headache and dizziness.

How to prevent Pellagra?

Eating a well-balanced diet is the simplest way to stay well-nourished. If food choices are limited, fortified foods and dietary supplements can help. About 15 milligrams of niacin per day is enough for a healthy adult. This amount is usually obtained from a B-complex vitamin supplement. Some of the foods that are most rich in niacin include:

• Beef liver
• Beetroot (Beets)
• Brewer's yeast
• Enriched bread and cereals
• Oily fish, such as salmon and tuna
• Peanuts
• Potato
• Poultry
• Rice
• Sunflower seeds
• Spaghetti sauce

If you have a chronic health condition that makes you more likely to develop pellagra, talk to your doctor about ways to prevent it in the long term. This may include making changes to your diet, supplements, or medications you take.

How long does it take to recover from Pellagra?

When you start taking niacin supplements, most people start to feel better within a few days. Digestive symptoms (like diarrhea) tend to improve first , usually within the first week. Skin and mouth sores can take up to two weeks to heal. Some severe cases may take longer. Severe nerve damage and dementia may be irreversible. To prevent further primary pellagra, doctors recommend maintaining a balanced diet. Niacin deficiency often goes hand in hand with other micronutrient deficiencies. All of these can be corrected with a good diet. Treating secondary pellagra can be a bit more complicated. While supplements can help, if the body can't metabolize niacin properly, that help may not be enough. In such cases, recovery depends on identifying and treating the underlying condition that caused the pellagra. This can be a long process, depending on the disease.

Finally, things to remember (Take-Home Message)

Although primary pellagra has largely been eliminated from developed countries, it still exists among poor people with limited food. In countries like ours, secondary niacin deficiency remains a risk due to alcohol use and certain medical conditions (especially those that interfere with nutrient absorption).

The most important thing is to remember that although nutrition starts with food, it ends inside the body.Many things inside your body need to be working properly. If you have any symptoms that suggest something is wrong, especially if you have problems with your digestive system, be sure to seek medical advice. Even a small vitamin deficiency can have a big impact on your health. So, eat a balanced diet, live a healthy lifestyle, and see a doctor as soon as possible if you have any problems.
