    Happens to me sometimes. Tried slow release but it bloated me and gave me constipation. Now have ordinary one fairly early in day and watch what I eat.

    I think its grin and bear it! After 13 weeks of taking 1500 a day it is much more spasmodic. I can go for days without anything then it's back. I keep a food diary but cannot really find any link. It's very unpleasant and I am scared stiff of being caught out! So far I have been lucky!

    Some people are intolerant of Metformin but reading through posts on the forum, some find they have less symptoms if they take it halfway through a meal and others have said that too many carbs start the symptoms off.
    You need to keep a food diary and see if you can pinpoint when the side effects occur and if it is related to any foods that o eat.

    I'll tag @daisy1 to give you some basic information that will help you manage your condition.

    Hello and welcome to the forum :) Here is the information, mentioned above, which we give to new members and I hope you will find it useful. Ask as many questions as you like and someone will be able to help.


    Diabetes is the general term to describe people who have blood that is sweeter than normal. A number of different types of diabetes exist.

    A diagnosis of diabetes tends to be a big shock for most of us. It’s far from the end of the world though and on this forum you’ll find over 150,000 people who are demonstrating this.

    On the forum we have found that with the number of new people being diagnosed with diabetes each day, sometimes the NHS is not being able to give all the advice it would perhaps like to deliver - particularly with regards to people with type 2 diabetes.

    The role of carbohydrate

    Carbohydrates are a factor in diabetes because they ultimately break down into sugar (glucose) within our blood. We then need enough insulin to either convert the blood sugar into energy for our body, or to store the blood sugar as body fat.

    If the amount of carbohydrate we take in is more than our body’s own (or injected) insulin can cope with, then our blood sugar will rise.

    The bad news

    Research indicates that raised blood sugar levels over a period of years can lead to organ damage, commonly referred to as diabetic complications.

    The good news

    People on the forum here have shown that there is plenty of opportunity to keep blood sugar levels from going too high. It’s a daily task but it’s within our reach and it’s well worth the effort.

    Controlling your carbs

    The info below is primarily aimed at people with type 2 diabetes, however, it may also be of benefit for other types of diabetes as well.
    There are two approaches to controlling your carbs:

    • Reduce your carbohydrate intake
    • Choose ‘better’ carbohydrates

    Reduce your carbohydrates

    A large number of people on this forum have chosen to reduce the amount of carbohydrates they eat as they have found this to be an effective way of improving (lowering) their blood sugar levels.

    The carbohydrates which tend to have the most pronounced effect on blood sugar levels tend to be starchy carbohydrates such as rice, pasta, bread, potatoes and similar root vegetables, flour based products (pastry, cakes, biscuits, battered food etc) and certain fruits.

    Choosing better carbohydrates

    Another option is to replace ‘white carbohydrates’ (such as white bread, white rice, white flour etc) with whole grain varieties. The idea behind having whole grain varieties is that the carbohydrates get broken down slower than the white varieties –and these are said to have a lower glycaemic index.

    The low glycaemic index diet is often favoured by healthcare professionals but some people with diabetes find that low GI does not help their blood sugar enough and may wish to cut out these foods altogether.

    Eating what works for you

    Different people respond differently to different types of food. What works for one person may not work so well for another. The best way to see which foods are working for you is to test your blood sugar with a glucose meter.

    To be able to see what effect a particular type of food or meal has on your blood sugar is to do a test before the meal and then test after the meal. A test 2 hours after the meal gives a good idea of how your body has reacted to the meal.

    The blood sugar ranges recommended by NICE are as follows:

    Blood glucose ranges for type 2 diabetes
    • Before meals: 4 to 7 mmol/l
    • 2 hours after meals: under 8.5 mmol/l
    Blood glucose ranges for type 1 diabetes (adults)
    • Before meals: 4 to 7 mmol/l
    • 2 hours after meals: under 9 mmol/l
    Blood glucose ranges for type 1 diabetes (children)
    • Before meals: 4 to 8 mmol/l
    • 2 hours after meals: under 10 mmol/l
    However, those that are able to, may wish to keep blood sugar levels below the NICE after meal targets.

    Access to blood glucose test strips

    The NICE guidelines suggest that people newly diagnosed with type 2 diabetes should be offered:

    • structured education to every person and/or their carer at and around the time of diagnosis, with annual reinforcement and review
    • self-monitoring of plasma glucose to a person newly diagnosed with type 2 diabetes only as an integral part of his or her self-management education

    Therefore both structured education and self-monitoring of blood glucose should be offered to people with type 2 diabetes. Read more on getting access to bloodglucose testing supplies.

    For me it was off and on. Have to say best thing about coming off Metformin though was a regular stomach again. Go see your Doc if it's playing up, most people seem to be the slow release version.

    I have a problem I am incredibly sensitive and even after three years I still get bouts of Diorreah even with the SR tablets and to make it worse they have now reformulated it and we are getting different shaped round tablets that even though they say are the same they are not. I am having to go through the regime as if I am starting again with them taking one round one and one oval one as the new ones really upset me. Why do they need to change it. It is one of the most disgusting drugs I have ever come across but is necessary to keep my diabetes under control. I can only hope that eventually my body will get used to the new form.
