Hi I'm new here and thought I'd ask those who have diabetes and I gather 'experts; on diabetes...
For about 5 years now I've had or been prone to hypoglycemia. The last few weeks though I've had both lows (in the 3's) and highs (10-11.5). I have symptoms of both to go with the number, when I'm in the 3's which only happens with long periods of not eating or exercise, I get bad headaches, tired, sweaty, , confused, lack of concentration and feel very weak.
With the higher numbers I feel quite thirsty (usually find I drink 4-5 glasses of water in one go) and sick.
The highs however only tend to happen when I eat and am low at the time. E.g. the other day I was 3.6 after 7 hours of nothing to eat from lunch to dinner as well as exercise (one 30 min jog and 1 20 min walk jog after lunch and walk before dinner) in between. I ate dinner (only 16g of carbohydrates sweet potato, capsicum and fish) and 2.5 hours later I was 11.1 I washed hands and double checked and got 11.3, this is certainly not the first time. This has never happened in the past I?ve never gone even above 6 even with low numbers, normally I?d stay 3-5mmol.
Anyway, I'm active, jog 30-40 mins most days, play tennis twice a week 2 hours on a Wednesday night and 2 hours on Sunday morning but cut down the last 10 days or so b/c of being really tired and no energy. I eat between 80-90g carbs a day (none from sugary food or soft drinks though), am not overweight (5ft 2 and weigh only 88lbs) actually nearly all bone really I?ve lost 3 kilos in 2 weeks. I have a pretty strong family history of type 2 diabetes and type 1 though the type 2?s in my family have a really hard time losing weight. I also in the last 2 years have a hx of steroid induced diabetes where my numbers go into the high teens and 20?s and have used/been prescribed insulin for it but im guessing that is a common problem anyway??
Could it (now) be an early stage of diabetes or still a problem of hypoglycemia??
