An intravenous pyelogram (PIE-uh-low-gram), also called an excretory urogram, is an X-ray exam of your urinary tract. An intravenous pyelogram lets your doctor view your kidneys, your bladder and the tubes that carry urine from your kidneys to your bladder (ureters).
By Mayo Clinic Staff. Low potassium (hypokalemia) has many causes. The most common cause is excessive potassium loss in urine due to prescription water or fluid pills (diuretics). Vomiting or diarrhea or both can result in excessive potassium loss from the digestive tract. Only rarely is low potassium caused by not getting enough potassium in your diet.
Abnormal Potassium Levels. The body requires a precise balance of potassium. Not getting enough potassium or getting too much potassium may cause problems in the body. Low levels of potassium may cause symptoms such as fatigue, muscle cramps, constipation and bloating. Without increasing levels, the condition may cause paralysis in the muscles and abnormal heart rhythms.
