Colds are generally divided into two types: bacterial infections and viral infections. Common symptoms include headaches, a runny nose, and muscle aches throughout the body. However, some patients may also experience symptoms such as ordinary diarrhea, which is medically referred to as a gastrointestinal cold. For treating a gastrointestinal cold, it is important to first determine whether it is caused by bacteria or a virus. Treatment should involve the use of anti-cold medications to target the pathogen, along with anti-diarrheal medications to alleviate the symptoms.
