Vitamins
and mineral supplements are important both in preventing deficiency
states as well as in preventing diseases. Most diseases resulting from vitamin deficiencies such as scurvy (vitamin C deficiency), blindness (vitamin A deficiency), and beriberi (thiamine deficiency)
occur mainly in third-world countries and are almost nonexistent in the United
States. But certain special populations in the United States can develop vitamin
or mineral deficiencies, and thus require dietary supplements. For example,
severely malnourished alcoholics can develop nerve damage from thiamine
deficiency;
pernicious anemia is a
condition, along with nerve damage, than can result from vitamin B12
deficiency; and
people with celiac sprue can also develop vitamin deficiencies as well as iron deficiency.
For these special populations, vitamin supplements are
important to prevent these deficiencies.
Vitamins supplements to prevent diseases
Vitamin supplements are not only used to prevent deficiencies but also used to prevent diseases. Certain vitamin supplements (such as folic acid, vitamin B6, and B12) have been used to lower blood levels of homocysteine, which may help prevent heart attacks. Folic acid fortification in cereals and vitamin supplements has been found to decrease the risk of birth defects in women of childbearing age.
Diets to control and or treat diseases
Diets low in simple sugars are important in controlling
blood glucose levels in people with diabetes mellitus. When the condition cannot be
adequately controlled by diet alone, medications (sometimes including insulin) are required.
The DASH dietis recommended to lower blood pressure. If dietary measures alone are not sufficient, medications are frequently prescribed by doctors (sometimes in combination) to lower blood pressure.
A gluten-free diet is the primary treatment for celiac disease (celiac sprue). Since people with celiac sprue may have difficulty absorbing nutrients and vitamins, some people with this condition may also need calcium, iron, and vitamin supplements.
Therapeutic lifestyle changes (TLC) are important treatments for
high blood levels of cholesterol, especially the "bad" ( LDL) cholesterol. When TLC are not sufficient, then medications are usually indicated to lower blood lipid levels.
High blood pressure, also known as hypertension, is a repeatedly
elevated blood pressure exceeding 140 over 90 mmHg -- a systolic pressure above
140 with a diastolic pressure above 90. There are two causes of high blood pressure, primary and secondary. Primary high blood pressure is much more common that secondary and its basic causes or underlying defects are not always known. It is known that a diet high in salt increases the risk for high blood pressure, as well as high cholesterol. Genetic factors are also a primary cause. Secondary high blood pressure is generally caused by another condition such as renal hypertension, tumors, and other conditions. Treatment for high blood pressure is generally lifestyle changes and if necessary, diet.
Diabetes mellitus is a chronic condition characterized by high levels of sugar (glucose) in the blood. The two types of diabetes are referred to as type 1 (insulin dependent) and type 2 (non-insulin dependent). Symptoms of diabetes include increased urine output, thirst, hunger, and fatigue. Treatment of diabetes depends on the type.
Heart attack happens when a blood clot completely obstructs a coronary
artery supplying blood to the heart muscle. A heart attack can cause chest pain, heart failure, and electrical
instability of the heart.
Learn about osteoporosis, a condition characterized by the loss of bone density, which leads to an increased risk of bone fracture. Unless one experiences a fracture, a person may have osteoporosis for decades without knowing it. Treatment for osteoporosis may involve medications that stop bone loss and increase bone strength and bone formation, as well as quitting smoking, regular exercise, cutting back on alcohol intake, and eating a calcium- and vitamin D-rich balanced diet.
Cancer is a disease caused by an abnormal growth of cells, also called malignancy. It is a group of 100 different diseases, and is not contagious. Cancer can be treated through chemotherapy, a treatment of drugs that destroy cancer cells.
Pernicious anemia is a blood disorder in which the body does not make enough red blood cells due to a lack of vitamin B12 in the blood. Pernicious anemia can develop from a lack of a protein that helps the body absorb vitamin B12, not getting enough B12 in the diet, and certain intestinal conditions that interfere with the absorption of vitamin B12 such as Crohn's disease, celiac sprue, or ulcerative colitis. There is no cure for pernicious anemia, thus treatment is life-long.
Obesity is the state of being well above one's normal weight. A person has traditionally been
considered to be obese if they are more than 20 percent over their ideal weight.
That ideal weight must take into account the person's height, age, sex, and
build.
Vitamins are organic substances that are essential for the proper growth and functioning of the body. Calcium is a mineral essential for healthy bones and is also important for muscle contraction, heart action, and normal blood clotting.
Birth defects have many causes and currently, are the leading cause of death for infants in the first year of life. Some of the causes of birth defects include genetic or chromosome problems. Exposure of the mother to rubella or German measles during pregnancy, or using drugs or alcohol during pregnancy. The treatment for birth defects depends upon the condition of the effected child.
Pregnancy planning is important to help prevent exposure of the mother and fetus to potentially harmful medications and substances during the early days, and throughout the pregnancy. Nutritional planning, prevention of birth defects, conditions such as high blood pressure, heart disease, diabetes, and kidney disease need careful monitoring. Gestational diabetes, preeclampsia, and pregnancy induced hypertension are conditions that may arise during pregnancy. Immunizations, inherited disorders, exercise, air travel, intercourse, and birth control are important factors to consider when planning a pregnancy.
Heart attacks are the major causes of unexpected, sudden death among men and women. A heart attack is also a significant cause of heart failure. Learn the risk factors for heart attack such as high blood pressure, diabetes, and other heart conditions. Lowering your risk factor, lifestyle changes, and in some cases medication are the most effective way of preventing a heart attack.
