9 Signs And Symptoms Of Vitamin B12 Deficiency.

One of the most common nutritional deficiencies humans experience is a B12 deficiency. Two of the biggest factors that contribute to having a B12 deficiency are actually things that people do in order to improve their health: weight-loss surgery and having a strict vegetarian diet. Considering that the B12 vitamin is responsible for lots of things going on in your body, there are plenty of symptoms to look for. Keep scrolling to find out what some of those symptoms are and maybe you can find an answer to some questions you've been having about your own health.

One of the biggest signs of a B12 deficiency is unexplained fatigue.

Because your red blood cells aren't able to carry oxygen throughout your body, you'll find yourself exhausted or even light-headed. There are lots of things that could make you tired, but if it's a constant thing, make sure you contact your doctor.

One way your body shows that you have a vitamin deficiency is by experiencing changes in your behavior or mood.

Not having enough B12 in your body affects the amount of serotonin your brain produces. Serotonin is one of those "happy chemicals" that your brain creates, so it's extremely important that you're producing enough of it. If you feel that your B12 production could be affecting your mood, check in with your doctor. That bad mood that seems to be appearing every morning could be simply handled with some B12 supplements!

A common sign of a B12 deficiency is shortness of breath.

B12 is responsible for making hemoglobin, the protein that transports oxygen throughout your body. Lacking B12 could lead to your tissues not receiving enough oxygen, causing weakness and shortness of breath. It's important to contact your doctor immediately if you have heart palpitations, shortness of breath, or unexplained fatigue.

If you notice that your tongue is becoming beefy, red or smooth, then you could have a B12 deficiency.

When you don't have enough B12, your body's DNA synthesis becomes impaired. When this happens your mouth's epithelial cells begin to rapidly divide, causing glossitis, recurrent oral ulcers, angular cheilitis, and oral candidiasis. A change in your eating habits could fix this by adding some fortified cereals, fish, red meat, poultry, eggs, or milk to your diet. For vegan sources, add foods such as plant milks, breakfast cereals, soy products, and nutritional yeast.
