Vitamin B – ranging from B1, B2, B3, B5, B6, B7, B12, to folic acid – helps the body get or make energy from the food we consume, and is useful for forming red blood cells. Therefore, do not let our bodies not get enough intake of this vitamin, because lack of vitamin B can cause various kinds of diseases that we certainly do not want. Here are various problems that arise if the body is deficient in vitamin B.
Vitamin B1 (Thiamine)
This type of vitamin B deficiency can cause beriberi and Wernicke-Korsakoff syndrome. Beriberi affects breathing, eye movements, heart function, and alertness because the body cannot convert food into energy.
While Wernicke’s disease affects the nervous system and causes visual disturbances, lack of muscle coordination, and mental decline. If left untreated, Wernicke’s disease can cause Korsakoff’s syndrome which can permanently interfere with memory function in the brain.
Vitamin B2 (Riboflavin)
Vitamin B2 or riboflavin serves to help release energy from foods that contain carbohydrates; important for cell growth and repair; maintain healthy skin, eyes and nervous system; convert tryptophan to niacin (vitamin B3); help protect cells from free radicals; and help reduce fatigue.
If you lack this ‘B vitamin’, your body will lack other nutrients, because riboflavin has an important role in processing nutrients. Vitamin B2 is also important for pregnant women so that baby growth is not inhibited and reduces the risk of preeclampsia. Anemia, red eyes, cracked lips, mouth infections, to sensitive to light are signs that our body lacks vitamin B2.
Vitamin B3 (Niacin)
Without vitamin B3, the body will experience digestive disorders, thrush, fatigue, vomiting, until depression. If severe, this type of vitamin B deficiency can cause pellagra disease which is characterized by disorders of the skin, digestion and nervous system. If left untreated, this disease can cause death.
Vitamin B5 (Pantothenic acid)
Vitamin B5 deficiency is very rarely found because this vitamin is found in almost all types of vegetables and will not cause other health problems. But if it does, people who lack vitamin B will experience headaches, fatigue, irritability, impaired muscle coordination, and digestive disorders.
Vitamin B6 (Pyridoxine)
This type of vitamin B deficiency can lead to anemia and skin disorders, such as a rash or cracking around the mouth. Lack of vitamin B6 can also cause depression, confusion, nausea, susceptibility to infection, to increase the risk of colon cancer and other types of cancer.
Vitamin B7 (Biotin)
Although rare, a deficiency of biotin or vitamin B7 can occur during pregnancy, attacking malnourished patients, or those who experience rapid weight loss. Symptoms of a lack of vitamin B include hair loss, dry skin, scaly rashes around the eyes or mouth, dry eyes, fatigue, and depression.
Vitamin B9 (Folic acid)
Vitamin B9 deficiency can cause a decrease in the number of fetal red blood cells and cells in the womb. In addition, insufficient vitamin B9 in the body can also cause us to develop anemia. Symptoms of vitamin B deficiency are feeling tired, gray hair, mouth sores, poor body growth, and swollen tongue.
Inadequate amount of vitamin B12 in the body can make us anemic, loss of appetite, constipation, irregular heartbeat, until the breath becomes short. If it is severe, this vitamin B deficiency can also cause paresthesia (numbness, pain or itching sensation on the skin), increase the risk of heart disease and stroke, causing us difficulty moving, memory loss, delusions, depression, to dementia.
In order to avoid various symptoms and diseases caused by B vitamin deficiency, it is recommended to consume vitamin B from proteins such as fish, poultry, meat, eggs, dairy products, green leafy vegetables, and nuts.
