Thyroid hormone is used to treat underactive thyroid (hypothyroidism). It is a natural product made from animal thyroid glands (usually a pig's). It replaces or provides more thyroid hormone, which is normally produced by the thyroid gland.
Foods high in potassium include bananas, spinach, carrots and oranges. Decreasing potassium intake can cause levels in the body to drop, but this is not a common reason for a decrease in potassium levels. Low potassium levels can occur when the body loses too much fluid due to illness. This fluid loss may occur because of excessive amounts of vomiting and diarrhea.
A variety of foods contain potassium, which means that diet alone rarely causes low potassium levels. Potassium works closely with sodium to regulate cell function and these two electrolytes must stay in balance. Consuming large amounts of sodium increases your bodyâs need for potassium.
