    hi doc,

    i just came across your site, coz i am looking for a good endocrinologist in st. lukes. i have been seeing one in makati med, but i think that i want another opinion and another doctor who is nice and who would welcome any queries i had. i had my thyroid ultrasound last may and two small nodules was found. i hope you can recommend a good and a nice endocrinologist based in st. lukes or if there is one in makati med. thanks a lot!

  2. Doc Gerry Says:

    hello jeanie. I dont rec routine ultrasound of the neck without reason becuase with that u will find thyroid nodules which are not palpable nor clinically significant which we call Thyroid Incidentalomas. I am not sure how big they are. You can look for Rey Rosales. Hes a friend that I met in our conventions and gatherings.

I went to see an eye Doctor on April 21 and he diagnosed it as subconjunctival hemorrhage possible caused by the Pletaal you prescribed to replace the aspirin.I have stopped taking the Pletaal and would like to ask if I should continue or not?

    Dear Doctor Tan,
    I’m very interested to your informatively Web site.
    My father lives in Manila, is 76 years old and he got very sick in diabetes. His health condition is all in all very serious.
    Even a leg of him is to be amputated.
    Because you’re specialist in this field of diabetes you may give a recommendation for a specialist in Manila to me. Please help us immediately.
    Thank you very much for your kindness and God bless you.
    Yours sincerly,

  11. Doc Gerry Says:

    Joey… there a lots of great endocrinologists in Manila. I am trained in US so I particularly dont know their expertise to be exact. BUT your pa’s problem lies in not being able to seek consult at the proper time where the best time for a diabetic to check is before he becomes one and still at risk…LIKE YOU! Dont wait for symptoms or complicatiojs like the one your father has before you seek advise.

  12. April Kho Says:

    Hi Dr. Tan!
    I was diagnosed with toxic goiter last August when I was in Davao. However, my job compelled me to have my September consultation with Dr. Chang of CDO City. I’m supposed to consult him again this coming November 24. Unfortunately, I’m now assigned in Dumaguete and I’ve been having a hard time finding another endocrinologist. I’m hoping you can refer me to an associate. Going to Cebu is my last option. Thank you!

  13. Doc Gerry Says:

    There are endocrinologists in Dumaguete that you can visit. Try to get the opinions of local folks too who they would recommend

    I have a friend who wants to visit from the US. He is prescribed ritalin for his ADHD. He wants to know if this medication or generic product similiar is available in the philippines. Thank you

  36. Hi doc Gerry H. Tan. This is Mrs. Aclao who’s son was your patient more than 10 years ago. You told me “mrs. ayaw kabalaka kay tanan problema sa thyroid kinaon na nako”. Oh, i love your confidence. in other words you really are an expert in your field. and i didnt doubt that. As a second opinion doctor, you just based your order for total thyroidectomy from the biopsy result i brought from CDO. It was carcinoma. but then, days after my sons’ operation, the only explanation you gave us is that “sometimes sa atong paglakaw sa dalan sa dili nato damhon maigo ta sa kilat”. It’s like a sambingay. Mao ra to imong sulti after knowing that my son’s case is not carcinoma but LANGERHANS CELL HISTIOCYTOSIS. Only from other sources we learned that he may not be operated. SAYANG KAAYO!!! So at least now can you give us an explanation? Was there a mistake? who’s mistake?

    Hi Doc, I’m curious to ask. Can these be related to any endocrine problems.

    1. Having headaches for a week even with paracetamol the headache doesn’t go away.
    2. Having trouble concentrating for weeks
    3. Always tired
    4. Gaining weight (having problems losing weight)
    5. High blood pressure
    6. Feeling of something growing in my throat
    7. Pain at the right back at the end of my ribcage (could it be an Adrenal problem?)


    KUB ultrasound was found normal no stones.
    Others were just boarder line high.

    Can I get a consult from you to ensure what I’m experiencing isn’t endocrine problem? I need opinions to what I’m experiencing.
