You are definitely HIGH risk for diabetes. You need to have your blood sugar checked immediately and not wait. Symptoms like this, going for several months, as you say, could be damaging your organs, especially your eyes and kidneys. You need to have lab work done, and having a bad headache and dizzy spell that isn't going away is a SERIOUS danger sign, there could be swelling in the brain,. Do not put this off, even if it means going to the emergency room for a "headache". You could go into a coma.
With your dry mouth and thirst, what are you drinking??? IF you are using any juices or soda pop, your sugar could be extremely high.
One of my patients, several years ago had these same symptoms that developed in a matter of three weeks, drinking a gallon of orange juice within three days, and when he went to the ER nearly comatose, his blood sugar was 735, was put it the ICU.
He died in a short time, at the age of 27, too much damage was done to reverse the process.
If you don't go to the Dr. before Monday, and Monday is a holiday in most places, so you probably won't find Dr. office open to make an appt. ER's are open 24 hours.
If you are putting off getting checked out, .......(not a good idea). TODAY, go to any drug store or Walmart, buy an Accucheck Monitor (finger stick blood sugar test kit) so you can self test. There are instructions in them on how to use, but will likely only have 10 test strips, the strips are expensive if you buy separately. For Insurance to pay, you must have a prescription. The kit, is over the counter for anywhere from $12 to $25. The strips alone will be over $50, but most of the starter kits will have probably 10 strips. Have a pharmacist help you pick out.
Blood sugar ranges can vary for normal, but for an "average", it should be close to 80 to 110, even to 120. If you are in the 200's or above, go to ER or at least call your Dr and let them know what is going on, you might need to be admitted. IF your blood sugar won't register on the monitor, it may be TOO HIGH TO READ, get a LAB test at the hospital.
Please repost what happens or private message, I am concerned. Too bad if it interferes with your Christmas plans, but better safe than sorry.
