If your blood count is very low, you will likely feel dizzy and be pale. You might not have any energy. A simple blood test can tell you if you are anemic. Anemia can be caused by internal bleeding, by not getting enough iron in the diet, or even by some types of cancers that can also give you night sweats
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
Anemia is the condition of having less than the normal number of red blood cells or less than the normal quantity of hemoglobin in the blood. The oxygen-carrying capacity of the blood is, therefore, decreased. There are several types of anemia such as iron deficiency anemia (the most common type), sickle cell anemia, vitamin B12 anemia, pernicious anemia, and aplastic anemia. Symptoms of anemia may include fatigue, malaise, hair loss, palpitations, menstruation, and medications. Treatment for anemia includes treating the underlying cause for the condition. Iron supplements, vitamin B12 injections, and certain medications may also be necessary.
Iron and Iron Deficiency
Iron is a mineral our bodies need. Iron deficiency is a condition resulting from not enough iron in the body. It is the most common nutritional deficiency and the leading cause in the US. Iron deficiency is caused due to increased iron deficiency from diseases, nutritional deficiency, or blood loss and the body's inability to intake or absorb iron. Children, teen girls, pregnant women, and babies are at most risk for developing iron deficiency. Symptoms of iron deficiency include feeling weak and tired, decreased work or school performance, slow social development, difficulty maintaining body temperature, decreased immune function, and an inflamed tongue. Blood tests can confirm an iron deficiency in an individual. Treatment depends on the cause of the deficiency. Proper diet that includes recommended daily allowances of iron may prevent some cases of iron deficiency.
Dehydration is the excessive loss of body water. There are a number of causes of dehydration including heat exposure, prolonged vigorous exercise, and some diseases of the gastrointestinal tract. Symptoms of dehydration include headache, lightheadedness, constipation, and bad breath. Treatment for dehydration is to replace lost fluids and electrolytes.
Peptic or stomach ulcers are ulcers are an ulcer in the lining of the stomach, duodenum, or esophagus. Ulcer formation is related to H. pylori bacteria in the stomach, use of anti-inflammatory medications, and cigarette smoking. Symptoms of peptic or stomach ulcers include abdominal burning or hunger pain, indigestion, and abdominal discomfort after meals. Treatment for stomach ulcers depends upon the cause.
