Always Tired? Vitamin D, Anaemia and 3 Other Things a Sharjah GP Checks First
Feeling tired all the time is rarely “just stress”. In the UAE, the most common treatable causes a GP checks first are low vitamin D, iron-deficiency anaemia, high blood sugar, an underactive thyroid and poor sleep. A simple blood test can help tell them apart, so you treat the cause, not the tiredness.
“Doctor, I sleep eight hours and I still wake up exhausted.”
I hear this almost every day in my Sharjah clinic. Usually it comes with a sigh and an apology, as if being tired were a personal failing. People have tried more coffee, an earlier bedtime, a new supplement from a friend. Nothing worked, so they assumed it was just life.
It isn’t. Persistent tiredness is a symptom, and symptoms have causes. Many of those causes are common here, easy to test for and very treatable.
Why are so many people in Sharjah tired all the time?
Our lifestyle makes it easy to slip into a pattern. We move from air-conditioned home to air-conditioned car to air-conditioned office. We avoid the midday sun, for good reason. We work long hours, commute between emirates, stay up late on screens and eat on the run.
That mix explains why a few specific problems turn up again and again. None of them are dramatic, and all of them can leave you feeling flat.
What should a GP check first when you're always tired?
1. Is low vitamin D making me tired?
It can. Despite the sunshine, vitamin D deficiency is very common in the UAE because we spend so little of the day in direct sun. Low levels are linked with tiredness, low mood, muscle aches, and bone pain. Many people have it for years without knowing.
Most labs treat a level below about 20 ng/mL as deficient, with 20–30 ng/mL counted as low. Reference ranges vary slightly between labs, so let your doctor interpret your result.
2. Could it be anaemia?
Yes, and it’s one of the first things I look for, especially in women. Iron deficiency is the most common cause. Heavy periods, pregnancy, a diet low in iron, and some digestive conditions can all contribute. Low vitamin B12, more common in vegetarians and in people on certain diabetes medicines, can also cause anaemia.
The clues are tiredness, breathlessness on stairs, pale skin, dizziness, headaches, cold hands and feet, and sometimes hair shedding.
3. Is it my blood sugar?
The UAE has one of the higher rates of diabetes in the world. In the early stages, the only symptoms may be tiredness, strong thirst, frequent urination, blurred vision, or slow-healing cuts. Many people are in the “pre-diabetes” range without being told.
This one matters most because it’s the easiest to catch early and the most rewarding to reverse.
4. Is my thyroid underactive?
When the thyroid slows down, everything slows with it. You feel tired and cold, gain weight without changing what you eat, and notice dry skin, constipation, low mood, or irregular periods. It’s more common in women and is easy to confirm with a blood test.
5. Am I actually sleeping well?
Eight hours in bed isn’t always eight hours of sleep. Loud snoring, stopping breathing at night, waking with a headache or falling asleep in meetings can point to sleep apnoea, which is often missed. Late-night scrolling, caffeine after 3 pm and heavy dinners also cut the quality of your sleep.
Which symptom points to which cause?
| What you notice | A GP may suspect | Test usually advised |
|---|---|---|
| Tired, aching muscles or bones, low mood | Low vitamin D | Vitamin D level |
| Tired, breathless, pale, dizzy, heavy periods | Iron-deficiency anaemia | Blood count, ferritin, B12 |
| Tired, very thirsty, passing urine often | High blood sugar / diabetes | Fasting glucose, HbA1c |
| Tired, cold, weight gain, dry skin | Underactive thyroid | Thyroid function (TSH) |
| Tired, snoring, morning headaches | Sleep apnoea or poor sleep | Clinical review, sleep assessment |
This table is a guide, not a diagnosis. Symptoms overlap, and many people have more than one cause at once. That’s why one set of blood tests is more useful than guessing.

What can you do this week to feel better?
These are the things I tell patients to start straight away, before the results come back:
- Keep a 7-day diary. Note your sleep times, meals, caffeine and energy levels. It gives me patterns I can’t get from memory.
- Don’t self-prescribe. Please don’t start high-dose vitamin D or iron because a friend did. Too much can cause harm, and the right dose depends on your actual level.
- Eat for iron. Include lentils, chickpeas, spinach, red meat or fish, and pair them with vitamin C such as lemon or peppers. Keep tea and coffee away from iron-rich meals, since they reduce absorption.
- Get safe daylight. A short walk in early morning or late afternoon light helps your body clock. Keep up your sun protection.
- Move for 20–30 minutes most days. Counter-intuitively, gentle regular exercise raises energy.
- Protect your sleep. Same bedtime daily, screens down an hour earlier, no caffeine after mid-afternoon, and an earlier, lighter dinner.
- Drink enough water. Mild dehydration in our heat is a quiet cause of fatigue and headaches.
When should you see a doctor about tiredness?
Book a visit if tiredness lasts more than two to three weeks, or sooner if it’s getting in the way of work, driving or family life.
See a doctor promptly, without waiting, if you have any of these alongside the tiredness:
- Chest pain, palpitations or severe breathlessness
- Unexplained weight loss
- Black or bloody stools, or very heavy periods
- Persistent fever or night sweats
- Fainting or severe dizziness
- Feeling hopeless or low for weeks
