Internal Medicine
Feeling constantly tired, weak, or mentally foggy is not always just a sign of a busy schedule. Sometimes, it can point to a vitamin deficiency that quietly affects energy, nerves, and overall health.
Vitamin B12 is an essential vitamin that helps the body produce healthy red blood cells, maintain nerve function, support brain health, and convert food into energy. When levels are too low, symptoms can develop gradually and may be easy to overlook at first.
At Mubadala Health Dubai, our Internal Medicine specialists provide comprehensive assessment and personalized treatment for Vitamin B12 deficiency, helping identify the cause, restore healthy levels, and reduce the risk of long-term complications.
Vitamin B12 plays an important role in several essential body functions. It supports healthy nerves, normal brain function, DNA production, and red blood cell formation.
Without enough Vitamin B12, the body may struggle to produce healthy red blood cells and maintain proper nerve function. Over time, this can affect energy levels, concentration, mood, balance, and overall wellbeing.
Vitamin B12 deficiency often develops slowly, which means symptoms may be subtle at first or mistaken for stress, poor sleep, or general tiredness.
Common symptoms include:
If left untreated, Vitamin B12 deficiency can lead to anemia, nerve damage, and cognitive changes. Early diagnosis and treatment can help prevent these complications.
Vitamin B12 deficiency can happen when the body does not get enough Vitamin B12 from food or cannot absorb it properly.
Possible causes and risk factors include:
Identifying the underlying cause is important, as some patients may need ongoing treatment or monitoring to prevent the deficiency from returning.
