Persistent loose stools for five months, with urgency two to three times daily, suggest chronic diarrhoea, which requires proper medical evaluation rather than only probiotics or antispasmodic medicines. Common causes include irritable bowel syndrome with diarrhoea, chronic intestinal infection, food intolerance such as lactose intolerance, bile acid-related diarrhoea, thyroid imbalance, or intestinal inflammation, and these cannot be confirmed without tests. Since symptoms are persistent and affecting your ability to go out, you should consult a gastroenterologist as soon as possible for stool tests, basic blood work, including thyroid function, and further evaluation if required, such as a colonoscopy, depending on findings. Your pacemaker does not directly cause diarrhoea, but your overall health, hydration status, and current medicines should be reviewed by your doctor to avoid dehydration and electrolyte imbalance risks. Until you are evaluated, maintain good fluid intake with oral rehydration solutions, eat simple, bland food, and avoid spicy, oily foods and dairy if it worsens symptoms. Do not continue changing medications on your own, as treatment depends on identifying the exact cause.
