Pale or yellow skin can be a subtle sign of vitamin B12 deficiency. Individuals with anemia may appear pale due to a lack of red blood cells. Jaundice, or yellowing of the skin and eyes, can occur due to the breakdown of red blood cells that are not effectively replaced by new ones in the event of a deficiency. These symptoms may be overlooked, especially in the absence of other obvious signs of illness.

Shortness of breath and dizziness
Many people ignore shortness of breath and dizziness, attributing these sensations to anxiety, panic attacks, or general fatigue. However, vitamin B12 deficiency can lead to anemia, which reduces the body’s ability to transport oxygen. This lack of oxygen can cause shortness of breath, especially during physical activity, and can lead to dizziness or lightheadedness, especially when standing up quickly.

Vision problems

Vitamin B12 deficiency can also affect vision, causing blurred or distorted vision due to damage to the optic nerve. This condition, known as optic neuropathy, can be misdiagnosed as age-related vision loss or other eye problems. If you experience vision changes alongside other symptoms, it’s important to seek medical advice, as early intervention can prevent permanent damage.

Mood changes
Vitamin B12 is involved in the production of neurotransmitters, which regulate mood and mental health. A deficiency can lead to symptoms of depression, anxiety and irritability. These mood changes can be mistaken for everyday stress or life changes. However, addressing vitamin B12 levels can significantly improve mental health and emotional well-being.
