It sounds uncomfortable to feel the urge to have a bowel movement but not be able to pass stool. This is a common symptom of constipation, which can sometimes occur after eating certain foods like pasta.

To help relieve your constipation, you can try the following steps:

• Drink plenty of water throughout the day to soften your stool.
• Include fiber-rich foods in your diet such as dals (lentils), vegetables, and whole grains like millets.
• Gentle physical activity, like walking, can stimulate bowel movements.
• Avoid delaying the urge to go when you feel it.

If these measures do not help, or if constipation persists beyond a couple of days, you might consider a mild laxative like Lactihep Plus Oral Emulsion, which contains ingredients that soften stool and stimulate bowel movements. However, this should be used only under a doctor's guidance and not for more than a week to avoid dependency.

If you experience severe abdominal pain, vomiting, or blood in stool, seek immediate medical attention by contacting a gastroenterologist.
