B12 injections and weight loss?

Ryaan profile image
16 Replies

Has anyone else noticed rapid weight loss with self injecting B12 ?

(I started with 1 a week for 10-12 weeks as it was very low and no help from GP, and now once every 2 weeks)

Not much of a diet change (as it wasn't that bad anyway, and no exercise added). Just with injecting B12. (A lot of change in weight).

I wasn't overweight so I'm just curious if anyone else has noticed.

I was the opposite unfortunately, lost a stone in the 6 months prior to PA diagnosis but started gaining again once I got injections.

Have you had your thyroid checked? There does appear to be some interaction between B12 and thyroid function.

I've lost some weight since si - about half a stone. I know it's because I'm not eating as much as before - my appetite has really waned. I have to force myself to eat, much of the time.

I noticed the lack of appetite, but don't feel the need to eat, just eat because u have to and try to eat a good diet.

B12 is enough to give you 101 symptoms and hard to deal with, The last thing I want is a lack of something else.

hi crystal54 here i have gained lots of weight since starting injections i am on 3 monthly but i am so short of breath i have been for tests for breathlessness but they say nothing wrong yet i can't do much without being out of breath i think I've had pa for a few years without being diagnosed as i was dizzy and clumsy and tripping over feet all the timebut i didn't go to doctor until i thought i was having a heart attackand straight away she took blood and next day phoned for me to go see her i was put on injections straight away but 2 years down the line i still don't feel great i am 63 years old and feel like ninety i think everyone reacts different thats why I'm glad i found this forum now i know im not the only one thank you all for your posts and i wish you all well in the future

Have you had your Ferritin levels and Folate levels checked as if they’re Low you get shortness of breath.

Even if you’re within the range but on the lower side of the range it still happens.

Get a printout of blood results and post on here or read them yourself.

Don’t trust the doctor with blood results, most won’t tell you anything’s wrong unless your deficient (lower than the range).

Breathlessness is usually caused by low Folate or low Ferritin (Iron) or can be both.

Also your 3 monthly injection might not be enough as I self inject every 2 weeks.

Took me 4 months of 1 weekly injections before I felt better in the start.

Also make sure your Vitamin D levels are ok.

If 3 monthly injections are not enough for you (depending on how low your B12 was) that could also be the cause of breathlessness.

That is breathlessness whilst you’re stationary and not doing anything.

I lost about a stone before diagnosis and it's slowly creeping back on.

I have lost 3 stone in three years since starting treatment

Mind you I needed to lose it I think it's because I have more energy now

Could be the case. I was very Inactive due to low B12 and no energy before SI.

Hi

Yes it's worth checking your thyroid but I agree( privately) - I had more energy - that and I stopped eating gluten.

How are you feeling and sorry to ask but how much is a lot?

Yes the Dr'S are useless but their hands are tied in the NHS. The RDA limits for most vitamins was set up in 1941. Just a tad behind Japan and other forward thinking countries!

A lot ?

You mean weight ?

I lost about 10kg in last 6 months. To me it seems a lot.

Ryaan in reply toHoward39

Sorry forgot.

I feel much more energetic and a lot of other symptoms have gone, some improved. My main symptom now is fatigue. I'm not taking any Iron, I think I was on the low side and that's causing it, also was low on D3.

Hi

They both need to be optimal.

Vit d makes a massive difference- take it with K2 mk-2.

It's definitely worth the £99 blue horizon fee that will give you a reading on all thyroid and 11 vitamins- it is private and comes directly to you.

Yes that is a fair amount of weight loss- depends whether you can afford to lose it. Definitely needs monitoring- just need to ascertain reason as I have never heard of it being b12 and you certainly don't want that taken off you.

Daft question but how is your diet- good fats are your friend. Most of my clients have to alter eating habits.

If you need any help message me

K2 is Potassium, what is K2 my-2 ?

What does it do, does work together with D3.

Is blue horizon a private blood test ?
