Hi After hearing your history i would advise you to treat anaemia with iron supplements and making changes to your diet. If the underlying cause of iron deficiency is loss of blood — other than from menstruation — the source of the bleeding must be located and stopped. This may involve surgery. Treatment for folic acid and B-12 deficiency involves dietary supplements and increasing these nutrients in your diet. If your digestive system has trouble absorbing vitamin B-12 from the food you eat, you may need vitamin B-12 shots. At first, you may receive the shots every other day. Eventually, you ll need shots just once a month, which may continue for life, depending on your situation. For loss of appetite:you have to do the following test an ultrasound of your abdomen a complete blood count tests of your liver, thyroid, and kidney function (these usually require only a blood sample) an upper GI series, which includes X-rays that examine your esophagus, stomach, and small intestine a CT scan of your head, chest, abdomen, or pelvis In some cases, you will be tested for pregnancy and HIV. Your urine may be tested for traces of drugs. If your decreased appetite has resulted in malnutrition, you may be given nutrients through an intravenous line. Your doctor may also prescribe oral medication to stimulate your appetite. Your doctor may refer to you to a mental health specialist or counselor if your loss of appetite is a result of depression, an eating disorder, or drug misuse. Loss of appetite caused by medications may be treated by changing your dosage or switching your prescription. Never change your medications without first consulting your doctor. If your decreased appetite is caused by a short-term condition, you’re likely to recover naturally without any long-term effects. However, if your decreased appetite is caused by a medical condition, the condition could worsen without treatment. If left untreated, your decreased appetite can also be accompanied with more severe symptoms, such as: extreme fatigue weight loss a rapid heart rate fever irritability a general ill feeling, or malaise If your decreased appetite persists and you develop malnutrition or vitamin and electrolyte deficiencies, you can have life-threatening complications. Therefore, it’s important to seek medical attention if you have anorexia that does not resolve after an acute illness or that lasts longer than a few weeks.
