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.
The most common cause of high potassium is kidney failure. When your kidneys fail, they canât remove extra potassium from the body. This can lead to potassium buildup. Another possible cause of high potassium is heavy alcohol or drug use, which can cause your muscles to break down. This breakdown can release a high amount of potassium into your blood from your muscle cells.
