Millions of People Search for These Questions Every Month in Turkey
Now, when we get sick, the first thing we do is not run to the doctor, but type into Google from our phone. An average of 8-10 million people search for "general health information" every month in Turkey. “How to strengthen immunity?”, “What causes fatigue?”, “I cannot lose weight, is my metabolism slow?” Questions like these are always at the top of the list. It's only natural that so many people wonder the same things; Because modern life has made us both more conscious and more anxious. However, most of the information on the internet is either incomplete or completely wrong. In this article, we explain the 15 most searched general health topics in Turkey in 2025 with scientific facts and information that you can easily apply to daily life. Our aim is not to scare you, but to provide you with accurate information.
How to Strengthen the Immune System?
Immune boosting is the undisputed number one search for general health information. Everyone thinks, "I should drink vitamin C so I don't get sick," but the reality is much different.
Vitamin C does not strengthen immunity, it only normalizes the system weakened by its deficiency. Your daily need is 75-90 mg; One orange already covers this. Taking 1000-2000 mg tablets a day will only cause expensive urination.
True immunity friends are:
- 7-9 hours of quality sleep (70% of immune cells are renewed during sleep)
- Vitamin D (90% of adults in Turkey are deficient, ideal blood level is 40-60 ng/mL)
- Zinc (meat, pumpkin seeds, chickpeas) – shortens the duration of colds by 33%
- Probiotic and prebiotic foods (yoghurt, kefir, pickles, onion, garlic)
- Regular but not excessive exercise (150 minutes of moderate-paced walking a week is sufficient)
Your immune system is like an orchestra; It becomes strong not with a single vitamin, but with the harmony of all parts.
What are the symptoms of vitamin deficiency?
“Am I vitamin deficient?” The question is in second place. It is necessary to learn the 5 most frequently deficient vitamins and their symptoms in detail.
Vitamin D deficiency: Inability to get up in the morning, muscle-joint pain, hair loss, depressed mood, frequent illness. B12 deficiency: Tingling in hands and feet, forgetfulness, burning in the tongue, unsteadiness in walking. Iron deficiency (anemia): Constant feeling of cold, pitted nails, hair loss, palpitations, desire to eat ice. Magnesium deficiency: Eyelid twitching, muscle cramps, insomnia, irritability. Folic acid deficiency: Canker sores on the tongue, weakness, depression.
If you have 3-4 of these symptoms, you should go to the doctor and have a blood test. Blindly taking vitamin pills can damage your liver and kidneys.
What Causes Fatigue? Anemia or Thyroid?
The word “fatigue” is searched more than 1 million times every month in Turkey. If you have a feeling of fatigue that does not go away even if you drink coffee, and even an afternoon nap is not enough, there may be 4 main reasons:
- Iron deficiency anemia (most common)
- Hypothyroidism (thyroid sluggishness)
- B12 and folic acid deficiency
- Chronic fatigue syndrome / fibromyalgia
If your fatigue lasts longer than 3 weeks and there are symptoms such as hair loss, coldness, constipation, be sure to have a "complete blood count + thyroid panel + B12 + ferritin" analysis.
I Can't Lose Weight, Is My Metabolism Slow?
This question is the biggest question on the minds of 80% of women. The sentence "My metabolism is very slow, no matter what I eat, I gain weight" is not true.
The truth is this: In adulthood, the metabolic rate slows down by 2-3%, which means a maximum of 1-2 kilos per year. If you cannot lose weight, there is a 90% chance that you cannot create a calorie deficit. A daily deficit of only 500 calories is enough to lose 0.5 kg per week.
Things that really slow down metabolism:
- Extremely low-calorie diets (the body goes into famine mode)
- Muscle loss (muscle ratio decreases with age)
- Hypothyroidism (slows down if left untreated)
- Lack of sleep (as sleep decreases, the ghrelin hormone increases, the feeling of hunger increases)
When is a Headache Dangerous?
96 out of every 100 people experience a severe headache at least once in their life. Although most are tension-type or migraines, some are signs of serious illness.
“Red flag” symptoms that require immediate medical attention:
- If it's the worst headache of your life
- If there is vomiting, vision loss, speech disorder
- If there is weakness or numbness in the arms or legs
- If there is fever, stiff neck
- If it has just started over the age of 50
How to Relieve Constipation? Permanent Solutions at Home
Constipation affects 1 in every 4 people in Turkey. If you go to the toilet less than 3 times a week, you are constipated.

- 2.5-3 liters of water (fiber without water is useless)
- 30 minutes of walking every day (increases bowel movements by 30%)
- 1 glass of warm water + 5-6 dried apricots on an empty stomach in the morning
- Magnesium citrate (with doctor's recommendation)
Sleep Problem: Why Can't I Sleep?
Searches for “sleeping problems” increased by 150% with the pandemic. 35% of adults wait at least 1 hour to fall asleep every night.
10 golden rules of sleep hygiene:

Causes of Numbness and Tingling in the Hands

What Causes Constant Cold?
