Other signs and symptoms of B12 deficiency

B12 insufficiency can cause the following symptoms in addition to the ones listed above:

• Muscle aches and pains, as well as muscle weakness: B12 deficiency can cause muscle cramps and weakness by impairing motor and sensory neuron function.
• Coordination problems: B12 deficiency can cause ataxia, or decreased balance and coordination, which is a neurological symptom. As a result, a B12 deficiency can make walking and balance difficult.
• Erectile dysfunction: This is a condition that affects men. As a result of elevated homocysteine levels in the body, men with B12 deficiency may have erectile dysfunction.
• Vision problems: B12 deficiency can cause vision problems, possibly due to optic nerve damage.
