Hi Pippa,
Yes - we all panicked on diagnosis, & we have to change diet, BUT the changes we make should be changes for the better, so that once we get to grips with the condition our general health improves. I was just turned 60 when diagnosed now I'm nearly 70 & still play a good game of tennis.
No need to panic - good control prevents diabetic complications & in any case it takes years.
Were you told any numbers? You can ask for a printout of your blood test results.
Look for HbA1c, which is your average blood sugar level for the last 2-3 months. Non-diabs will be below 5.5, above 10 needs medication.
As far as eating is concerned "they" will tell you "low sugar, low fat, low salt" & to eat comlex carbohydrates - brown basmati rice, multigrain bread, pasta, etc, at every meal, including breakfast cereals like porridge & Special K & Albran. Fruit juices are high sugar & should be avoided.
My experience (& that of many on the forum) is that that diet is not the best, & carbohydrates should be greatly reduced. Eat more protein (cheese, meat, nuts) & vegetables, other than potatoes.
Ask your Dr or nurse about a test meter AND test strips on prescription. Readings should be 4-6 overnight & 6-8 two hours after food.
I'm surprised that the medication is starting so soon, & building up to 4 a day. Usually they try you on diet to see what control is possible.
