Hello All,
I am a newbie here, so please excuse me for being naive.
I had been on beta blocker (Propranolol 80mg) for my migraines from 2009 to 2016...and I had been monitored for the usual ailments every year via a blood test..Since 2015 my sugar had been on rise (nearly 8.5 on fasting), I have a feeling (and various researches also confirms) that the beta blocker is the culprit behind my BG rise..
In 2016 the Propranlol was discontinued as it didnt work as it should, so I was put on Amitriptyline, and this raised my heart rhythm to over 150 (sitting idle), so to counteract this I was given Bisoprolol (which calms the heart down)..so I am still on these 2, and was wondering if the betablocker could cause the high BG, latest HB1ac is 57!

thanks for your help everyone.!

regards
sam

Hi @waterboy72,

Welcome to the forum. I will tag @daisy1, who will post some brilliant information for newbies.

I've just done a quick search on the link between betablockers and diabetes and found some evidence for this. This is the site I found: http://diabetesupdate.blogspot.de/2008/09/beta-blockers-worsen-blood-sugar-may.html. By the way, the information Jenny Ruhl posts is generally pretty reliable.

However, we will probably never know for sure what has caused our diabetes and in the end it probably doesn't make too much of a difference. What matters is how we deal with it.

Are you on any medication for your diabetes?

Have you had a look at the low-carb diet to control your blood sugar levels? For many of us, this has been extremely helpful. If not on insulin or any medication to increase insulin production, a low-carb diet tends to be safe.

There is also anecdotal evidence that a low-carb diet may help with migraines. (Searching the dietdoctor.com website will probably give you some more info on this.)

Hello Sam and welcome to the Forum :) Here is the Basic Information, referred to above, which we give to new members and I hope you will find it helpful. Ask as many questions as you like and someone will 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 235,000 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.

Yes, Beta Blockers do raise blood sugar levels. There is quite a bit of research about this, but it depends which one you are taking. They don't all cause problems. Two of the worst culprits are Atenolol and Propranolol. They can also slightly increase triglycerides and decrease high-density lipoprotein (HDL, or "good") cholesterol.

Poor grammar, bullying and drunks.
Amitriptyline causes raised blood glucose levels in some people. It certainly impacted on mine.
It takes some fishing but if you Google the name of a drug and hyperglycaemia you can find out if there is evidence of raised bg levels.

Welcome waterboy! When I was first diagnosed I went through many reasons why? Was it my shift work? Was it my gallstone problems? Was it medications I was on? But I quickly decided I would drive myself mad dwelling on it. There was nothing I could do apart from get on and deal with it. I have gone low carb and self monitored along with taking Metformin and my last three HbA1c tests have been non diabetic. This Forum has, apart from educating me on Type 2 and how to deal with it, taught me to question Drs prescriptions and put more thought into not just accepting them without researching the drugs.

I have been on the lowest dose of Atenolol since December. I have noticed a definite increase in my levels, particularly morning fasting. I did the research and mentioned it to my GP. After some discussion he said to wait till my next HbA1c and that it would be "an interesting academic experiment". Playing with my health is not interesting, to me. My research showed it increases insulin resistance and interferes with insulin production in the pancreas. As I hope to be off them fairly soon, and as I have none of the other side effects and they are working, I intend to stay as I am for now.

There are other newer beta blockers that work differently.

carvedilol, a nonselective beta-blocker had vasodilating and insulin-sensitizing properties, and is the ideal beta-blocker for the patient with diabetes

I've taken inderal or propranolol for more years than I can count, but it'd only recenly (in the last four years) that I've ended up with diabetes. I';m now no longer on any meds for this, I eat a low carb diet, which actually helps prevent most (manily) food related migraines and reduces others to a very infrequent occurrence with very low levels painwise. My glucose levels currently vary between very low pre-diabetic and just on normal now, so I've not seen any evidence thart the propranolol has caused me any diabetic issues. Though I'm happy to point my finger for those at a longish term (but not my choice of) high carb diet, and a longer term use of statins - finally refusing to take these any longer definitely reduced my glucose levels,
