Many conditions can cause stomach or abdominal pain, nausea or dizziness. Coexisting abdominal pain, nausea and vomiting, however, suggest an underlying condition that may require medical attention. A person with these symptoms should visit a physician to determine the cause of his complaints and to establish an appropriate treatment plan to resolve the problem.
POTS syndrome can cause abdominal pain, nausea and dizziness. According to the National Institute of Neurological Disorders and Stroke, POTS syndrome or postural orthostatic tachycardia syndrome, is one of several disorders that are characterized by orthostatic intolerance. Orthostatic intolerance is a condition in which a significantly reduced amount of blood returns to the heart after a person stands up from a lying position. The NINDS states that researchers are not sure of the exact cause of POTS syndrome, although the condition may be caused by abnormalities in the sympathetic or parasympathetic nervous systems. Common signs and symptoms associated with POTS syndrome include abdominal pain or discomfort, nausea and vomiting, dizziness, constipation, a headache and muscle weakness, among others. According to the NINDS, POTS syndrome symptoms come and go over many years.
Cholecystitis can cause abdominal pain, nausea and dizziness. Cholecystitis is an inflammation of the gallbladder. The gallbladder is a small, pear-shaped organ that sits just below the liver in the abdominal cavity. The gallbladder is responsible for storing bile--a substance that's released into the small intestine to aid digestion. The most common cause of cholecystitis is gallstones that obstruct the tube leading out of the gallbladder. Obstruction of this tube causes an accumulation of bile within the gallbladder, which in turn causes inflammation. Other possible causes of cholecystitis include infection, injury and tumors. Common signs and symptoms associated with cholecystitis include severe upper right abdominal pain, nausea, vomiting and dizziness, profuse sweating, abdominal tenderness and bloating and loss of appetite. If left untreated, cholecystitis can cause serious health complications.
Meniere's disease can cause abdominal discomfort, nausea and dizziness. According to the National Institute on Deafness and Other Communication Disorders or NIDCD, Meniere's disease is an inner ear abnormality that causes numerous symptoms. Meniere's disease typically affects only one ear and is a common cause of hearing loss. Many experts believe that Meniere's disease is caused by an inner ear rupture that allows two different types of inner ear fluid to mix. Meniere's disease symptoms usually manifest suddenly and can occur daily or as little as once per year. Common signs and symptoms associated with Meniere's disease include abdominal discomfort, vertigo or whirling dizziness, nausea and vomiting, sweating, tinnitus or ringing in the ears, headache and diarrhea. The NIDCD states that, although there is no cure for Meniere's disease, the disease's symptoms can usually be successfully managed by avoiding caffeine and alcohol and reducing salt intake.
