Always Tired? Weak Muscles? Palpitations? Common Deficiencies Behind Them
Some of the questions Dr. Amr Elyamany hears most are about everyday symptoms that patients cannot explain. Here are seven, with the deficiency that is commonly involved.
Symptoms and common causes
- Tired after the slightest effort: low iron is a common cause of exhaustion.
- Constant muscle weakness: low vitamin D affects muscle strength.
- Blurry vision: vitamin A deficiency can be a cause.
- Sudden palpitations: low potassium or magnesium is often responsible.
- Constant sleepiness: low vitamin B12.
- Always craving salty food: possible low sodium or magnesium.
- Eyelid twitching: low magnesium is the usual cause.
Two important warnings
Blurry vision and palpitations need a medical assessment: they can come from problems that have nothing to do with nutrition, and potassium in particular should not be taken as a supplement without medical advice, because too much can affect the heart.
What to do
Ask your doctor about tests for iron, vitamin D, vitamin B12 and electrolytes. Then correct any deficiency through food first, with supplements chosen for you if they are needed.
Key takeaway: These are clues, not diagnoses: the test tells you what your body is really missing.
When to see a doctor
- Palpitations that are frequent or come with dizziness, chest pain or breathlessness
- Any change in your vision
- Weakness that makes everyday tasks difficult
