Hemorrhoid injection treatment usually refers to injection sclerotherapy for hemorrhoids, in which sticky blood may appear in the stool after the injection treatment. After injection sclerotherapy, a sterile inflammatory response develops around the hemorrhoids and hemorrhoidal mass, which in turn causes fibrosis of the submucosal tissues, and eventually results in the hemorrhoidal mass atrophying, necrotic, and detaching. During this process, when the patient has a bowel movement there may be sticky blood. After the injection of sclerotherapy, it is possible that the desired therapeutic effect will not be achieved and multiple injections will be needed for treatment. Sticky blood when passing stools during this period is usually caused by the hemorrhoids themselves. Patients with hemorrhoids should develop good living and eating habits, both in their daily diet and during treatment, while avoiding spicy and stimulating foods as much as possible. In the event of discomfort symptoms, should promptly seek medical attention to avoid delaying the aggravation of the condition .
