Hi
@WilliamG,
I am pretty much cutting and pasting a comment I made to someone in a similar position a couple of days ago. Sounds lazy but I think it's valid to you. I have limited knowledge of these eye issues, but I am not aware of any real problems with metformin and eye-drops clashing, and I am confident that your doctor would know that.
It's tough at first to know what the hell to eat. Be reassured - Type 2 is definitely controllable and many of us here manage to keep what were high levels down to the normal range purely though diet; other with meds or a combination of both meds and diet. It's important I don't beat you to death with loads of detail, but good I think to know some basics as early as possible (so you can get a handle on it all and be relaxed with it.
1] LEVELS. What are your blood sugar levels like? The doctor will probably have had an HbA1c blood test done on you. It establishes the average level of your blood sugar over the preceding 3 month period (and is pretty accurate). Tests done with a little meter instead just give the level at a given point (and while less accurate, can be used to let you know when something is good or bad for your blood sugar level).
2] METERS.Do you have a self-testing meter? It's important to test regularly...more than the doctors advise (they don't want us getting stressed by readings). I strongly advise you keep a diary of what you eat and when, and that you record readings before eating and 2.5 hours after eating. That way you will quickly figure out what works. The post meal reading should be very similar to the premeal; if not the grub has too many carbs in it. if you haven't been given one, ask, but not all Type 2s are given one. In which case - buy one (check them out blood sugar self testing meters on the Amazon site). A meter (and testing strips..very easy to use - honestly) along with the record you keep is your greatest weapon next to being focused.
3] CARBS. There are other opinions, obviously, but lots of us are on a low carb high fat diet (LCHF) and cutting carbohydrates will lower your blood sugar a swell as assist with weight loss.
High or "simple" carbs turn into sugar in the blood and have the same impact as sugar. Personally, I do not eat bread, pasta, rice or spuds...no biccies, no cakes...etc. No cereal - it's brutal! But, seeing for yourself using a meter will inform you more (eg. my level will jump ridiculously after just one bit of toast!).Check the labels for what's in every 100g -.if the carbs are 10g or less per 100g - it's low carb....enjoy it!
4] FOOD. I eat: slices of smoked cheese (no carbs at all) and dried bacon slices for brekkie; boiled eggs or omelettes are good too. The odd fry up is fine. I often have 5 or 6 strawberries with an avocado and mayo for lunch.. For dinner, I eat steak, bacon, pork, chicken, 90% meat sausages, or fish (without batter). Salmon and tuna are good for you - oily fish has the good fat you need. All low or complex carb veg is ok. As a rule, if veg grows above ground its cool. I eat broccoli, cauliflower, spinach, lettuce, cabbage etc. Note that asparagus can lower the blood sugar level a bit.
I even have a beer with dinner. Red wine works for some people. A wee glass of whisky is good too. the liver copes with alcohol as a priority, so this delays it dealing with glucose.
Coffee and tea are fine - avoid too much milk. 90% cocoa dark chocolate (Lindt) is good. Nuts (particularly brazil nuts, hazelnuts and a few others) are fine in moderation and again help with right kind of fat.
As an afterthought - I allow myself an ice lolly after dinner if my pre-meal level is ok (ok..so its 2 lollies!). And, recently, I am having the odd croissant.
Explore the low carb info on this site. If you have any questions - you will get a response. It's all much more basic than it seems at first. best advice is - meter, test, record, cut carbs, persist. Good luck. Paul
. Metformin takes time to build up in your system and you might begin to see a slight effect. Never take Metformin on an empty stomach always take it with or after meals. Diet and Exercise will have an effect on helping to lower blood sugars too. As pleinster has already said about LCHF Diet take a look at the following:
