Discharge Instructions for Hypomagnesemia
You have been diagnosed with hypomagnesemia. This means you don't have enough magnesium in your blood. Magnesium is a mineral. It helps your body work normally. It helps you form bones. It helps muscles and nerves work. And it helps enzymes and hormones work. A very low magnesium level can be serious and lead to seizures and abnormal heart rhythms. And it can lead to a heart attack. Other symptoms can include:
- Nausea or vomiting.
- Sleepiness.
- Weakness.
- Personality changes.
- Muscle spasms or tremors.
- Loss of appetite.
Diet changes
You'll need to eat more foods that contain magnesium. These include:
- Dark green leafy vegetables, such as salad greens, spinach, kale, chard, and collards.
- All nuts and nut butters, including peanuts, almonds, pecans, cashews, Brazil nuts, macadamia nuts, peanut butter, and almond butter.
- Sunflower seeds.
- Pumpkin seeds.
- Milk, chocolate milk (prepared from powder mix), and eggnog.

Other home care

- Tell your doctor about all the medicines and herbal supplements you take. This includes prescribed and over-the-counter medicines. Some of them can lower your magnesium levels.
- Take all medicines as directed.
