PASCO -- U.S. Rep. Doc Hastings' office announced Monday that the 70-year-old Republican is being treated for diverticulitis at a Tri-City hospital.
Hastings, serving his ninth term in Congress, checked into the hospital Sunday morning while at home in Pasco. Officials are not saying which hospital.
His treatment is expected to take several days. He will remain in the area while recovering.
Hastings is in good spirits and looks forward to returning to work as soon as medically advisable, his office said.
Diverticulitis is a swelling of an abnormal pouch in the intestinal wall, often the large intestine or colon. The National Institutes of Health reports that the cause of the disorder generally is unknown, although a low-fiber diet might be a culprit.
More than half of Americans older than 60 have abnormal pouches in the intestine, but only a small percentage experience inflammation.
Symptoms include tenderness, usually in the left lower side of the abdomen; bloating; fever and chills; nausea and vomiting; not feeling hungry. Treatment depends on the severity of symptoms, and can include rest, pain medications, antibiotics and a high-fiber diet.
