Can vitamin b12 deficiency cause weight loss?

I've been feeling quite weak and noticed some unexplained weight loss. My doctor suspects a vitamin B12 deficiency. Can vitamin B12 deficiency actually cause weight loss?

Actually yes, because when B12 is super low, it completely kills your appetite and makes you feel nauseous. I couldn't even look at my favourite butter chicken last year because of this deficiency, which led to sudden weight loss. Once the doctor fixed my levels, my cravings and weight came back to normal!

Yes, many people experience unexpected weight loss with B12 deficiency because it affects the digestive system, leading to diarrhea or a loss of taste. I have seen this in my family too. Please visit a doctor soon to get the right supplements so your nutrition stays balanced.

Ho na, low B12 causes poor absorption of food in our body, which leads to weight loss. It actually makes you feel very weak. A simple blood test will tell you the exact picture, then the doc will guide you on the next steps.

Beta, if you are losing weight without trying, it means your digestive fire is weak due to this deficiency. While you must see a doctor for proper medicine, try drinking warm milk with a little turmeric daily to soothe your stomach. Do not ignore sudden weight changes at this stage.

Deficiency can make you lose weight because of constant loss of appetite, but trust me, this is the worst way to diet! You feel like a walking zombie all day. Better to get some B12 in you and lose weight the right way at the gym!

Oh God, I went through this and got so scared thinking it was something very serious like cancer because of the sudden weight loss. Turns out it was just a severe B12 deficiency messing with my gut health. Please don't stress yourself out, just book a blood test to clear your doubts.

I completely understand how terrifying it feels to watch the scale drop for no apparent reason, it really messes with your mental peace. I felt so hopeless when it happened to me, but finding out it was just a highly treatable B12 deficiency was such a relief. Take a deep breath, it is going to be okay once you get tested.

Haan, bilkul ho sakta hai. Jab sharir me taqat nahi rehti aur bhukh lagna band ho jata hai, toh vajan apne aap girne lagta hai. Aap bilkul chinta mat kijiye, bade doctor ko dikhakar ek khoon ki jaanch karwa lijiye, sab theek ho jayega.
