Multiple ulcers in the duodenal bulb are not serious in stage H1, which is a healing ulcer and not an active ulcer. Relatively speaking, ulcers in the active stage are the most serious, and complications such as bleeding, perforation, and obstruction can occur at any time. If the patient has been examined by electronic gastroscopy and the current ulcer lesion belongs to the H1 stage, it means that the ulcer is in the healing stage and is a stable ulcer, but the patient still needs to continue to cooperate with the medication until the ulcer is completely healed. If the patient stops or reduces the medication on his own with poor compliance, it may cause the healing ulcer to re-emerge and become an active ulcer, and then the condition will be very serious. Patients must pay attention to this, and also need to cooperate with the doctor to continue to use medication.
