St. Lucia hotels offer dramatic scenery and are usually beachfront. While these don't have the privacy of a villa, they do come with a lot of perks, including concierge or hotel staff services, access to pools and beaches, and many have restaurants, shops, and bars as well, like Rendezvous on Malabar Beach.
Early signs are nausea, diarrhea, and muscle weakness. As potassium levels increase, marked cardiac changes are observed in the electrocardiogram. Treatment of severe hyperkalemia includes oral administration of Kayexalate (sodium polystyrene sulfonate) and IV administration of sodium bicarbonate, calcium salts, and dextrose.
Hypermagnesemia is an electrolyte disturbance in which there is a high level of magnesium in the blood. It is defined as a level greater than 1.1 mmol/L. Symptoms include weakness, confusion, decreased breathing rate, and cardiac arrest. Hypermagnesemia can occur in kidney failure and those who are given magnesium salts or who take drugs that contain magnesium (e.g. some antacids and laxatives).
