Dealing with difficulty passing stools for three years suggests chronic constipation. For gentle, temporary relief, you can use bulk-forming laxatives like Psyllium husk, or osmotic laxatives such as Polyethylene Glycol or Lactulose, which help soften stools and ease passage. However, because this has been an ongoing issue, it is highly recommended to consult a doctor for a proper evaluation rather than self-medicating long-term. A physician can rule out underlying causes and safely guide your treatment. In the meantime, try increasing your dietary fiber gradually, drinking plenty of water, and staying physically active to help naturally stimulate your bowel movements.
