Intermittent distention of the abdomen may be caused by excessive formation of intestinal gas, but also physical or functional obstruction of the intestines. Belching and flatulence (farting or passing gas) are virtually universal. The maximum number of farts for a normal person is 20 per day.
Samoa is a Polynesian Pacific country northeast of Fiji. Samoa consists of four inhabited and five uninhabited islands. The capital Apia is located on Upolu, the most populous and developed of the islands. Upolu and Savai'i, the other main island, account for 99 per cent of Samoa's 195 000 population.
Samoa is about one-half of the way between Hawaii and New Zealand. The islands have narrow coastal plains with volcanic, rocky, rugged mountains in the interior. The two main islands are Upolu and Savaii. The capital, Apia, and the international airport are on Upolu.
