Some believe the syndrome is caused by iron anemia or folic acid deficiency. The symptoms can also be linked to other underlying conditions such as diabetes, rheumatoid arthritis, or Parkinson's disease. Some drugs can make RLS worse such as antidepressants, calcium blockers, anti-nausea medications, anti-allergy drugs, and even too much caffeine.
RLS may be helped by ensuring your diet has a good amount of iron, folic acid, calcium, potassium, and magnesium. Hence, a healthy diet, as promoted on this website, is your best ally. Cutting back on stimulants like caffeine, nicotine, and alcohol can also help. Be sure to stay well hydrated by drinking plenty of water. Try having a light slow-release snack like crackers and cheese or yogurt before retiring for bed to maintain blood sugar levels. It is believed that low blood sugar may play a part in RLS.
Calcium and magnesium supplements may prevent cramping and twitching. Omega-3 fish oils, ginkgo biloba, and garlic all help to boost circulation. Many of these dietary essentials are promoted on this site and can be found in Phase I and Phase II diet plans.
Walking, stretching, and yoga may also help to relieve your symptoms. If your leg movements are stopping you from sleeping, try massaging your legs or get up and walk around for a bit. Do be sure to let your healthcare provider know to understand all alternatives available.
