You have been diagnosed with hypophosphatemia (not enough phosphorus in your blood). Phosphorus helps develop bones and teeth. It also helps control energy metabolism. Most cases of hypophosphatemia are caused by other health problems.

• Unless your doctor tells you otherwise, drink at least 8 glasses of water every day.
• Keep track of how much fluid you drink.
• Eat more foods that contain phosphorus.
  • Increase your intake of milk, cream, cheese, cottage cheese, yogurt, puddings, custard, and ice cream. Add powdered milk to foods.
  • Eat meat, fish, poultry, eggs, and peanuts and other nuts and seeds. Also eat beans, lentils, peas, and soy products.
  • Eat bran cereal, granola, oatmeal, and wheat germ.

• Resume your normal activities as directed by your doctor.
• Tell your doctor about all prescription and over-the-counter medicines you are taking. This includes vitamins and herbal preparations. Some of these may cause interactions with other medicines.
• Tell your doctor if you have a history of diabetes or liver, kidney, or heart disease.
• Take all medicine exactly as directed. In some cases, your doctor will prescribe oral phosphate supplements if you have any condition that affects how your body handles phosphate.
• Don't take antacids that contain calcium, magnesium, or aluminum. They may keep you from absorbing the phosphorus that's in your food. Niacin can also interfere with absorbing phosphorus that's in your food.

• Make a follow-up appointment with your doctor, or as directed.
• Keep all appointments for lab work and follow-up. Your doctor needs to watch your condition closely.

• Confusion.
• Irritable behavior.
• Pain in your muscles.
• Nausea or vomiting.
• Diarrhea that is not relieved by antidiarrhea medicine or by changing your diet.
