Hi Dear !! Thanks for your query to HCM.
I understood your health concerns.
My Impression-
Based on facts of your query,You seems to suffer from-
Undiagnosed
Diabetes.
Though you are maintaining the weight with meticulous diet schedules,You don't seem to have any earlier check for diabetes,as you did not take it seriously to your doctors and so remained un-diagnosed.
Huger is from lower blood sugars,as you don't get breakfast.
Dizziness is from
Hypoglycemia, due to lowering of Blood sugars,from delayed intake of food.
I would suggest You to check your fasting / post-prandial and
HbA1c to understand the blood sugar problem over last 3 mths.
Hope this would help you to plan further care with your doctors there.
Keep Me updated whenever needed , 24 x 7, to help you out by even,online tips for You, on weekly basis.
Welcome for any further query in this regard.
Good Day!!
