Introduction
Pellagra is a systemic disease. It occurs due to a severe lack of vitamin niacin (vitamin B3). It influences the entire body and can ultimately prompt demise. Niacin deficiency is the root cause of primary pellagra. It typically occurs in populations that are hungry and poor. When the body cannot absorb the niacin from the food, people may experience secondary pellagra.
What Is Pellagra?
Niacin, also known as vitamin B3. A deficiency of niacin is the cause of pellagra. Micronutrient undernutrition is a type of malnutrition. Niacin is necessary for the functioning of cells in the body, and if people do not have enough of it, they will experience symptoms in the skin, mouth, bowels, and brain. Pellagra can cause permanent damage to the nervous system and even death if not treated. Niacin is present in several foods, and most people who eat a well-balanced diet get enough of it. Primary pellagra is, as yet, a huge issue in ruined and food-restricted populations. In the industrialized world, secondary causes, health conditions, or substances that prevent the body from absorbing or using niacin are more likely to cause niacin deficiency.
-
Primary Pellagra: When a person's diet lacks niacin or tryptophan, they experience this kind of pellagra.
-
Secondary Pellagra: This sort of pellagra happens when an individual's body can't ingest niacin.
What Is Niacin?
Niacin, a B3 vitamin, is what the body uses to turn food calories into energy. It is consumed through the digestive system into the body tissues, where it is switched over completely to a coenzyme called nicotinamide adenine dinucleotide (NAD). An agent for an enzyme is a coenzyme. Chemical reactions are catalyzed by it and enzymes. More than 400 different enzymes use the coenzyme NAD in the body.
The coenzyme NAD converts the potential energy in macronutrients like carbohydrates, proteins, and fats into energy that the cells can use (adenosine triphosphate, or ATP). It is essential to function in the cells and body systems that require more energy than others. DNA repair and cellular communication are other specific cellular functions involving NAD.
What Symptoms Does Pellagra Present?
The following are the symptoms of pellagra:
-
Chronic, bloody diarrhea.
-
Indigestion and pain in the abdomen.
-
Appetite loss, nausea, and vomiting.
-
Rashes on the skin that itch or hurt.
-
A red, swollen tongue as well as mouth sores.
-
Malaise, weakness, and fatigue.
-
Changes in mood and depression.
-
Neurological side effects such quakes or deadness and shivering in the hands and feet.
-
Dementia and delirium.
What Are the Causes of Pellagra?
A poor diet is the primary cause of pellagra. People can eat many foods to get vitamin B3, but people who need to eat more may not get certain nutrients. Secondary causes, or conditions that prevent the body from absorbing or using niacin, can also cause pellagra. Here are some examples:
-
Inflammatory bowel disease and liver cirrhosis are two examples of gastrointestinal diseases that result in malabsorption.
-
Disordered drinking Consuming alcohol can damage organs, resulting in malabsorption and general malnutrition, which can cause pellagra.
-
Surgery for a gastric bypass The intestinal mucosa can be damaged during bariatric surgery, resulting in various micronutrient deficiencies, including pellagra.
-
Lack of iron sickliness. Niacin conversion and utilization by your body require iron. The Hartnup disease. This hereditary problem keeps the body from engrossing amino acids, which are important to create nutrients from food.
-
Syndrome of cancer. Active tumor cells that inhibit niacin production are characteristic of this syndrome.
-
Antispasmodic and chemotherapy medications, in particular, can disrupt the body's niacin metabolism.
-
Niacin depletion is caused by HIV infection.
How to Diagnose Pellagra?
A doctor will examine the symptoms and medical history to diagnose pellagra and inquire about the diet. The doctor may order a urine test to confirm pellagra if they suspect it. They can tell if the body has enough niacin by looking at the levels of certain chemicals in the urine. Additionally, they might treat with niacin supplements to see if that helps confirm pellagra.
What Is the Treatment for Pellagra?
Pellagra is caused due to a lack of niacin (vitamin B3). It is treated with a supplement. Most people notice an immediate improvement when they take niacin supplements. For symptoms like mouth and skin sores, people might need more treatment. People will also require treatment for any previous health issues contributing to their pellagra.
How to Prevent Pellagra?
The simplest way to ensure adequate nutrition is to eat a well-balanced diet. Enriched foods and dietary supplements can help when there are few options for food. Niacin is sufficient for most healthy adults in a B-complex vitamin supplement. Niacin should be taken in approximately 15 milligrams per day. Regular checkups with doctors also help in the prevention of pellagra.
The following foods contain the most niacin:
-
Beef.
-
Beets.
-
Cereals and bread.
-
Fish (Salmon and Tuna).
-
Peanuts.
-
Potatoes.
-
Poultry.
-
Rice.
-
Pods of sunflowers.
-
Sauce for spaghetti.
What Is the Prognosis of Pellagra?
Supplements help in the prognosis of pellagra. Typically within the first week, symptoms in the gastrointestinal tract are the first to improve. Within two weeks, skin and mouth sores begin to heal. It may take longer for some advanced cases to heal. Dementia and severe nerve damage may never heal. The doctor recommends eating a well-balanced diet to prevent primary pellagra in the future. Other micronutrient deficiencies frequently accompany niacin deficiency. A healthy diet can help with all of these. Nutritional education or additional support may be required for some individuals. Treating secondary pellagra can be more difficult. If the body cannot metabolize niacin, even after taking supplements, they may not be sufficient. In these instances, recovery depends on identifying and treating the underlying condition causing pellagra. Depending on the condition, this procedure may take a long time.
Conclusion
Primary pellagra is extinct in developed countries. It is endemic in less-developed nations where food sources are restricted. Fortified food products, supplements, education, and other resources, could benefit these populations. Secondary niacin deficiency is still dangerous for people with alcoholism or other health conditions that make it hard for the body to use niacin. It is essential to remember that although diet plays a role in nutrition, the body is where most of the process must occur. Seek medical attention if people experience symptoms that indicate a problem, particularly with the digestive system. A small vitamin deficiency can quickly spread to other areas of the health.
