Signs that you are B12 deficient
Vitamin B12 performs several important functions in the body, deficiency of which can develop a number of heath issues. Vitamin B12 deficiency is defined by low levels of stored B12 in the body that can result in anemia, a lower-than-normal number of red blood cells. Your metabolism wouldn't run smoothly without it. B12 is majorly found in animal products like eggs, meat, shellfish, and dairy. Up to 15% of people don't get enough B12, and they're more likely to be vegetarians. Lets now look at the symptoms of B12 deficiency.
Some of the earliest signs of a deficiency include feeling dragged, confused, weak and dizziness. Since they can be attributed to so many other possible triggers, most people don't think to be tested. If these symptoms hit and stick around for weeks, it's best to consult your doctor and rule out other causes say experts. Fatigue is yet another major sign of B12 deficiency. That's because your body relies on the vitamin to make red blood cells, which carry oxygen to your organs. And without enough oxygen in your cells, you'll feel tired no matter how long you sleep.
Mood swings is another major symptom of lack of B12, as it wreaks havoc on your mood, possibly leading to depression or anxiety. Doctors say it may have something to do with the fact that B12 is involved in the synthesis of brain chemicals, such as serotonin and dopamine, that help regulate mood.
Also, B12 plays an important role in white blood cell production, and white blood cells are essential for proper immune system functioning. Not only can a lack of B12 lower your immunity, some immune system disorders can increase your likelihood of becoming deficient. Grave's disease, for example, an autoimmune condition of the thyroid causing hyperthyroidism, is a risk factor for developing pernicious anemia, which in turn leads to B12 deficiency.
