Metformin side effects

Mand1oo

Newbie
Hi all - new to forum was diagnosed with type 2 diabetes last week after 3 hba1c blood test results of 48 mol. Been taking metformin (500g) with my breakfast for past 4 days - 1 bout of explosive diarrhoea on 2nd day - but I'm finding that in the evening I'm feeling sick but almost like a hunger sicky feeling and I have a really dry mouth!! I'm due to start 2 tablets on Thursday and then 3 next week - are these symptoms normal and will they go away when my body adjusts to the meds???
 
Hi,
Welcome to the forum
I had to stop Metformin because of severe diarrhoea. For many the symptoms settle.
Has your dr told you that your pre-diabetic? It's unusual to start on Metformin.
Hope you feel better soon
Take care
 
If you are prepared to wait for the symptoms to possibly subside then continue. If you can not wait for that to happen, because of a long journey to work for example, then either go back to the Dr and ask for the Slow release version, wait before increasing the dose, or stop taking them and aggressively work on low carbing. The decision is yours, we do not know your medical history, your circumstances/lifestyle and therefore can not advise you further.
 
Give it at least a few weeks with metformin, some people find it better to take metformin with their evening meal, or 20 minutes before a meal, or 20 minutes after a meal. But give each experiment at least a week to see the result.

The Slow release version has less issues, but does not work as well, it also costs the NHS a lot more, hence doctors will try people on the normal version first.

@daisy1 will come along soon with the standard wellcome post that explains how carbs effect your blood glocuse levels. Controling your carb intake is key to good BG control, but metformin also help.

Hello Ringi and welcome to the Forum :) Here is the Basic Information we give to new members and I hope you will find it both interesting and helpful. Ask as many questions as you need to and someone will be able to help.


BASIC INFORMATION FOR NEW MEMBERS

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 well over 259,000 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

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.

Read more on carbohydrates and diabetes.

Over 145,000 people have taken part in the Low Carb Program - a 10 week structured education course that is helping people lose weight and reduce medication dependency by explaining the science behind carbs, insulin and GI.

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 blood glucose testing supplies.

  • Low Carb Program - it's made front-page news of the New Scientist and The Times. Developed with 20,000 people with type 2 diabetes; 96% of people who take part recommend it... find out why
  • Hypo Program - improve your understanding of hypos. There's a version for people with diabetes, parents/guardians of children with type 1, children with type 1 diabetes, teachers and HCPs.
 
I just had to give up the tablets after about 5 weeks of utter misery - I was on Metformin and a statin.
Since then I have perked up enormously, am going out several times a week and can remember where I left the car most of the time.

They are usually normal. I didn't have too many problems after the first couple of weeks; but I do seem to get caught out occasionally out of the blue and can't put it down to eating anything in particular. Generally they haven't been much of a problem
