Does MSG cause Butt Burn.No is the short answer. An outbreak of so called Kwoks Disease, an eponymous title from Dr Kwoks who first described it in the 1970s, was a severe flushing in patrons of Chinese restaurants in New York. It was attributed to Mono sodium Glutamate used to flavour Chinese foods in the USA. Subsequent research discovered no such association existed. But 'Although the tune is gone, the melody lingers on' in urban myth. So the answer is a definite No. Chinese food does not give you butt burn. But insufficient cleansing does. Even when initially there is no Perianal Soreness (PS) it can occur after a time because of weakness of the perianal sphincter with age or lack of fitness. The answer is to make sure there is 100% cleansing of the Perianal area with such as Baby Wipes followed by an effective skin protectant such as cavillon spray or cream. A pad such as a lady's eye pad with cream should be inserted to protect against leakage and to prove everything is clear.
