What is Nausea?
Nausea is a term that describes an uneasy feeling in the stomach, usually the need to vomit. The symptoms of nausea may include the urge to vomit, weakness, sweating, and a build-up of saliva in the mouth. The two most common causes of nausea and vomiting are stomach flu and food poisoning. The other common causes include early stages of pregnancy, seasickness and other forms of motion sickness, severe pain, being exposed to chemical toxins, emotional stress such as fear, gallbladder disease, indigestion, particular smells, certain medications, and general anesthesia. Pregnant women and patients who undergo cancer treatments such as radiation or chemotherapy have an increased risk of nausea and vomiting.
Nausea can be diagnosed through medical history, physical examination, blood test, urine test, or pregnancy test. Furthermore, the treatment options for nausea may include getting rest, staying dehydrated, steering clear of strong odours, avoiding other triggers (stuffy rooms, heat humidity, flickering lights), eating bland food, avoiding fatty or spicy foods, medicines (dimenhydrinate, meclizine, chewable or liquid antacids, bismuth sub salicylate, a solution of glucose, fructose and phosphoric acid), and alternative medicine (acupressure).
