I recently had tests done and they found a 3.7mm gallbladder polyp. My doctor told me not to worry and just to recheck it in 6 months to see if it grows, but didnt really explain why the polyp is there. Should I look into this more or just follow the doctors advice for now?

A 3.7mm gallbladder polyp is relatively small._Doctor's Recommendation_1. _Monitoring_: Your doctor's approach to monitor the polyp's size every 6 months is a reasonable strategy.2. _No immediate concern_: The small size of the polyp (less than 10mm) suggests a low risk of malignancy._Possible Reasons for Polyp Presence_1. _Cholesterol polyp_: Most gallbladder polyps are benign and composed of cholesterol.2. _Inflammatory polyp_: Inflammation in the gallbladder can cause polyp formation.3. _Other factors_: Genetics, obesity, and high cholesterol levels might contribute to polyp development._Further Investigation_1. _Not necessary for now_: Given the small size of the polyp, further investigation might not be warranted at this time.2. _Consider additional tests if_: You experience symptoms like abdominal pain, jaundice, or fever, or if the polyp grows significantly during follow-up._Consider a Second Opinion or Further Discussion_1. _Ask about polyp characteristics_: Discuss the polyp's characteristics, such as its shape, size, and location, with your doctor.2. _Understand the follow-up plan_: Clarify the follow-up schedule and criteria for re-evaluation.3. _Seek a second opinion if unsure_: If you're concerned or unsure about your doctor's approach, consider consulting a gastroenterologist or a general surgeon for a second opinion.
