why loose motion happens

Loose motion, also known as diarrhea, can be caused by a variety of factors. The most common cause of diarrhea is an infection in the gastrointestinal tract, which can be caused by a virus, bacteria, or parasite. Other causes of diarrhea include:
Food intolerances or allergies: Consuming foods that your body cannot tolerate or digest properly can lead to diarrhea.

Medications: Certain medications, such as antibiotics or laxatives, can cause diarrhea as a side effect.

Irritable bowel syndrome (IBS): IBS is a chronic condition that can cause diarrhea, constipation, and abdominal pain.

Inflammatory bowel disease (IBD): IBD is a chronic condition that causes inflammation in the gastrointestinal tract, leading to diarrhea, abdominal pain, and other symptoms.

Stress or anxiety: Stress and anxiety can cause diarrhea by affecting the way your digestive system functions.

Other medical conditions: Certain medical conditions, such as thyroid disorders, celiac disease, and pancreatic disorders, can cause diarrhea.
If you are experiencing diarrhea, it is important to stay hydrated and seek medical attention if your symptoms persist or worsen.
