A feeling of bloating in the small stomach is a common clinical symptom, and the reasons for these are many. For men, it may be due to holding urine or drinking too much water, and some bladder infections may lead to a feeling of bloating in the lower abdomen and small stomach. For women, the first thing you should consider is whether or not it is due to some gynecological or pelvic inflammatory disease, such as the common clinical adnexitis, pelvic inflammatory disease, etc. These cases often result in lower abdominal swelling and are accompanied by frequent and urgent urination, mostly due to infection factors. Some women also experience menstrual distension during or after menstruation and ovulation, which is often seen clinically. Therefore, it is best not to use special medication for the bloated belly formed during menstruation, but to gradually relieve the symptoms by paying attention to rest and diet and applying heat.
