More people are falling ill because of the scorching summer days. Hospitals across the country are reporting a 10 to 20 percent increase in patients, and doctors say a considerable number of them suffer from gastrointestinal problems.

According to a latest study published in The American Journal of Gastroenterology, scientists found that sustained periods of hot weather may cause symptoms related to gastrointestinal conditions, such as inflammatory bowel disease, to flare up.

It is known that high temperatures can directly affect human health given the mortality rates during heat waves.
