What are the possible side effects of senna supplements?

Common and mild side effects of senna include: stomach cramping or bloating, gas, mild diarrhea, slight numbness or tingling, joint pain and discolored urine and intestines. Most of these side effects should go away on their own, especially when you stop taking senna.

Seek immediate medical attention if you experience more serious side effects, including chronically painful joints, weakened bones and muscles, weight loss, ball-like endings to fingers and toes, severe stomach pain and diarrhea, nausea, itchy skin, decreased appetite, a worsening of constipation, dark urine and red stools and jaundice.

Some people have reported liver damage resulting from long-term use of senna. Others have seen a severe dip in potassium levels, which can result in confusion, abnormal heart rate and excessive thirst and urination. If you experience these side effects, seek immediate medical attention.
