Vitamin and Mineral Deficiency: Common Signs and When to See a GP

Vitamin and mineral deficiencies are common and can affect energy, immunity, and overall health. Symptoms often develop gradually and may be mistaken for stress or a busy lifestyle.

Common Signs of Vitamin Deficiency

Depending on the nutrient involved, symptoms may include:
 • Persistent fatigue
 • Pale skin or dizziness
 • Muscle weakness or bone pain
 • Tingling or numbness in hands and feet
 • Easy bruising or slow wound healing
 • Mouth ulcers or cracks at the corners of the lips

Iron deficiency, vitamin B12 deficiency and vitamin D deficiency are among the most frequently diagnosed in general practice

Who Is at Higher Risk?

You may be at increased risk if you:
 • Are pregnant or breastfeeding
 • Follow a vegetarian or vegan diet
 • Have digestive conditions affecting absorption
 • Have limited sun exposure
 • Are older or have chronic medical conditions

When to See a GP

Many of these symptoms can have multiple causes. A GP can assess your medical history, review risk factors, and arrange appropriate testing if required.

Avoid self-prescribing supplements without medical advice, as excessive intake of certain vitamins may cause harm.

If you have ongoing or concerning symptoms, seek personalised medical advice.
