Protein contains nitrogen which, when metabolized, leaves the body in urine. If the person has trouble excreting urine, like many patients

Dr. Ahmed was fantastic. Very friendly, very professional, very down to earth. Took time with me. Answered all my questions. I never felt rushed. Nicest doctor I have ever been treated by.
Dr. Sumar is very kind and treated ME with respect. I have a lot of anxiety and he really made it all comfortable as could be
Dr Tharalson is an excellent physician who listens carefully, asks relevant and incisive questions, delivers detailed explanations, and is accomplished technically.
He has been my wife's gastroenterologist for some time. I have a colonoscopy scheduled with him. I am (almost) looking forward to it ;)

We had a need to be seen soon after hospital dismiss. Got us in within 2 days. Very clean and organized office. Staff was helpful, pleasant, respectful, and kind. The doctor did not make us feel rushed, he addressed all our questions and concerns. I feel we are in good care with a complex situation. Tha k each one of you. ♥️
Everything turned out great thank God. I also thank Dr. Foley and staff for their expertise.
Dr. Lam, as well as all of the members of her team, were caring and supportive. All kept me engaged in the process along the way, respectfully ensuring I understood the information provided. Dr. Lam was clear in explaining the results and her recommendations. The entire experience was professional yet friendly and I will continue to use and recommend this group.
The staff is very professional and cheerful. We’ve been going there for years.
I've been a patient of Dr. Collins for quite a few years and couldn't be happier with the care he's provided me . He takes the time to talk about the results of my endoscopies immediately after the procedure and then again in follow up appointments. He also is interested in my general health. I should also say the staff there is also excellent. Dr. Collins is the best doctor I have ever had.
From the staff at reception to the medical staff and the Doctor, everyone was pleasant, knowledgeable and helpful. I highly recommend AZ Digestive Health on Eugie ave in Glendale.
My wife went to see him. Here is her review
The Dr was very pleasant and eager to help me. He is the first one in 5 years to help me. I am so happy. He spent time with me and listened. I will keep updating as tests get ordered.

The staff is knowledgeable and friendly. Dr Umar came into the room 5 minutes early and never seemed rushed. Answered all of my questions. I definitely would recommend this practice to anyone looking for a GI specialist

Great staff too

Excellent infusion experience
Dr. Walker listens and takes a holistic approach to managing my autoimmune disease, EOE. He doesn’t suggest additional EGD’s if symptoms are managed, but instead works with the patient to find the right medical treatments to mange the disease. He is very informative and takes the time to have a conversation.
I was impressed with Dr. CHUANG! Tammy Crawford, ADH staff member referred me to him. Tammy initially referred me to this ADH location in 2018. DR.CHUANG is relaxed and thrives with compassion. He relays concerns and explains suggestions in detail and with patience. He was impressed with progress I have shown since first diagnosed with Celiac disease in 2018 per Dr. Mary Atia. I felt loads of reassurance after seeing Dr. CHUANG on May 15, 2025.
He listens and he explains things ,also has a good sense of humor.I felt comfortable talking with him,I would recommend him.He showed me my picture of my problem and is doing a upper GI to see if it's healed.
He’s amazing! A REAL DOCTOR!
Dr. Stein and all the staff at East Valley endoscopy/Arizona digestive services,are top notch! They are polite, professional, and address all your concerns and issues.
Dr. Patel is great, he took his time listened to me and my concerns. I highly recommend him. Staff was very pleasant and courteous.
