Vitamin B12 deficiency can cause tiredness, weakness, constipation, loss of appetite. Some people also suffer from nerve problems such as tingling sensation in hands and feet and at times numbness.

People who can be more prone to this deficiency
Vegans: B12 is naturally found only in animal products and people who don’t take dairy products are more at risk.
People who drink alcohol regularly: Vitamin B12 is mostly stored in your liver and that balance can be disturbed by too much alcohol
People with acidity issues: People who take medicine for acidity can have vitamin B12 deficiency because the medicines to treat acidity can prevent your body from from absorbing it.
