We came to Dr. Guzman with our 4 year old son who has a rare disease (Eosinophilic Esophagitis) as well as numerous food allergies and environmental allergies. Our son would vomit up to 100 times a day. He was on medications for the disease, but we were seeing no improvement. Dr. Guzman was very thorough, understanding, and professional. He suggested we start him on BPC 157. After about 3 weeks, we noticed a great improvement in his vomiting. He went from a minimum of 10 times a day to no vomiting at all!! He is also able to expand his diet. His allowable foods were so limited due to his vomiting, but he is now able to eat apples, which he loves!! It has definitely given us hope for our son and his future! We can not thank Dr. Guzman enough!! We highly recommend Dr. Guzman for any of your medical needs.
