Frequent hiccups may indicate cancer, according to British experts.
According to the Daily Express, hiccups can occur due to eating too quickly, eating too much or drinking alcohol. However, in some cases, this symptom signals the occurrence of esophageal cancer.
Signs of cancer can appear if your stomach stops working properly and you notice that it is swollen for no apparent reason, said Dr. Hussain Abdeh.
Experts urge to seek medical attention if hiccups last more than 48 hours.
