After learning yoga, the frequency of defecation increases and is sparse. The possible reasons are as follows:

1. Unclean diet leads to gastrointestinal dysfunction or enteritis.

2. Yoga practice promotes blood circulation in the body, improves gastrointestinal function, promotes intestinal peristalsis, and leads to an increase in stool frequency.

Routine stool examination is recommended. If you have enteritis, you need to choose sensitive anti-inflammatory drugs for treatment. You can also find the tone of one pulse in Chinese medicine.

Please note that the above are only some possible reasons and cannot replace professional medical advice. If you continue to encounter this situation, it is recommended to consult a doctor or a professional health expert. They can provide you with accurate diagnosis and treatment suggestions.
