What are the best hospitals in Thailand for diabetic care under the 5-year multiple entry Medical Tourist Visa?

I would just like to enquire if any of our members are on on DTV 5year multiple entry Medical Tourist Visa. One of the requirements is a letter of invitation from a hospital in Thailand. I am looking at setting up in Jomtien area or south of their. I am a diabetic. Can you recommend a world class hospital possibly that has a section suited for diabetic care that I can inspect and ask for a letter?You not require medical insurance, but as a safety net I would like to be covered for incidents like road accidents , Physio, Choiro.I am assuming medical insurance may be difficult to get if you have a pre-existing condition like diabetes. I am reaching out as a diabetic as I monitor my HB1AC every 3 months, yearly ophthalmologist checks, podiatry checks, exercise programs, etc. I realise the Hospitals are all world class in Thailand, but I am looking at Specific diabetic treatment from members who suffer from this chronic disease. If you use annother facility , not in the Jomtien area of Thailand please share or PM me direct.If you could share a name of medical insurer that has the best benefits for Diabetes would be appreciated as well as a hospital clinic would be appreciated. I believe you need less money in the Thai Bank Account which means the rest of the money can be earning interest from the country come from. Please PM if you are on a Medical Tourist Visa.
