Always Tired? 10 Real Causes to Check Before Calling It Kamzori
“Kamzori hai” explains everything and nothing. Before you reach for a tonic, run through what is actually behind the tiredness.
Every desi household has a word for persistent tiredness that gets used for a dozen different problems: kamzori. It covers low iron, poor sleep, dehydration, stress, and sometimes an undiagnosed medical condition, all lumped into one vague complaint that gets treated with the same almond-milk-and-rest advice regardless of the actual cause. That approach sometimes works by accident and sometimes hides something worth catching early. Here is a structured way to check.
The short version
- Ten checkable causes below, roughly in order of how common they are.
- Iron deficiency and poor sleep account for a large share of “kamzori” complaints in adults.
- See a doctor if tiredness lasts more than two to three weeks despite fixing the obvious things.

The blood-test causes: iron, thyroid, sugar, vitamins
1. Iron levels, especially in women
Heavy periods, pregnancy, and a diet lighter on iron-rich foods make low iron common, and its main symptom is exactly this kind of dragging fatigue, sometimes with pale skin inside the lower eyelid, brittle nails, or unusual cravings for ice. A simple blood test (haemoglobin, and ferritin if you want the fuller picture) settles this in a day. Iron-rich foods like red meat, spinach with a squeeze of lemon (vitamin C helps absorption), lentils and jaggery help as ongoing diet, not as a substitute for supplements if a test shows you are genuinely deficient.
2. Thyroid function
An underactive thyroid slows the whole body down: tiredness, weight gain despite no diet change, feeling cold more than others in the room, dry skin, hair thinning. It is common enough, particularly in women over 30 and after pregnancy, that doctors will often check it alongside iron if fatigue has no obvious explanation. A TSH blood test is the standard first check.
3. Undiagnosed diabetes
High blood sugar pulls water out of cells and disrupts how the body uses glucose for energy, and persistent fatigue is one of its quieter early signs, often alongside excess thirst, frequent urination or slow-healing cuts. If tiredness sits alongside any of those, ask for a fasting blood sugar test.
4. Vitamin D and B12
Common in people who spend most daylight hours indoors, cover most of the skin outdoors, or eat mostly plant-based with little dairy or meat. Both are checkable with a blood test and both cause a specific, draggy kind of tiredness alongside, sometimes, tingling in the hands or feet for B12 deficiency.
The lifestyle causes: sleep, water, caffeine
5. Sleep debt that adds up quietly
Six hours a night feels manageable for a week. By week three, the tiredness has become the baseline, and you stop noticing it as unusual. Count your actual sleep for three nights honestly, not what time you went to bed but what time you actually fell asleep to when the alarm went off, and compare it to 7 to 9 hours.
6. Dehydration
Mild, chronic dehydration is an underrated cause of daytime fog and heaviness, especially in hot weather or if your day is mostly tea and cola rather than plain water. A rough check: urine should be pale straw coloured, not dark yellow.
7. Too much caffeine, badly timed
Chai and coffee late in the day can wreck sleep quality even if you fall asleep fine, leaving you tired the next day in a loop that looks like general kamzori but is really a caffeine-timing problem. Try cutting caffeine after 3pm for a week and see if anything shifts.
- Write down your actual sleep hours for 3 nights.
- Check urine colour once a day for 2 days (pale straw is the target).
- List any of: excess thirst, frequent urination, unusual cold sensitivity, hair thinning, tingling hands.
- If any box is ticked, or tiredness has lasted over 2 weeks with no clear cause, book a blood test covering haemoglobin, ferritin, TSH, fasting sugar, and vitamin D/B12.
The causes people rarely name
8. Depression and anxiety
Low mood does not always look like sadness. It often shows up first as exhaustion, loss of interest in things you used to enjoy, and difficulty concentrating, and it gets dismissed as “just tired” for months. If tiredness sits alongside low motivation, sleep changes in either direction, or a loss of appetite or pleasure, that combination is worth mentioning to a doctor specifically, not folding into a general fatigue complaint.
9. Medication side effects
Some blood pressure medicines, antihistamines and sleep aids cause daytime drowsiness as a known side effect. If tiredness started around the same time as a new prescription, that timing is worth mentioning rather than assuming it is unrelated.
10. Simply doing too much
Sometimes the honest answer is that the days are long, the responsibilities are real, and the body is asking for rest it is not getting, not a hidden diagnosis. That is a legitimate cause too, and it deserves an actual change in the week’s schedule, not a supplement to push through it.
Putting the checklist together in one sitting
Most people find it easier to work through this as a single honest evening exercise rather than spreading it over weeks of half-attention. Grab a notebook. Write down your average sleep hours across the last week, your rough daily water intake, whether your periods have been heavier than usual lately if that applies to you, and any of the checkable symptoms mentioned above: thirst, cold sensitivity, tingling, low mood. Seeing it all on one page, rather than as scattered worries, usually makes the next step obvious, whether that is a genuine lifestyle fix or a blood test appointment.
Unani medicine describes persistent fatigue partly through the lens of “za’f” or general weakness of the body’s vital strength, addressed through diet suited to a person’s mizaj (temperament), rest, and tonics like certain dried fruits and honey taken with warm milk. As everyday nourishment this is reasonable and often genuinely comforting; it was never meant to replace checking whether there is an actual deficiency or illness driving the fatigue, and a thoughtful hakeem would ask about diet, sleep and periods before reaching for any tonic.
See a doctor if fatigue has lasted more than two to three weeks despite reasonable sleep and hydration, if it comes with unexplained weight loss or gain, if you notice excess thirst or frequent urination, if you feel breathless doing things that never used to leave you short of breath, or if low mood and loss of interest are part of the picture. Pregnant women with persistent, unusual fatigue should mention it at their next antenatal visit rather than treating it as ordinary pregnancy tiredness, since anaemia is common and easily treated. Anyone on regular medication who notices new fatigue after a dose change should raise it with their prescriber rather than stopping the medicine themselves.
Frequently asked questions
Why am I always tired even after resting?
Constant tiredness usually has a checkable cause. Low iron and short or poor-quality sleep account for a large share, followed by thyroid problems, undiagnosed diabetes, low vitamin D or B12, dehydration, badly timed caffeine, low mood, medicine side effects, or simply doing too much. Work through them rather than calling it kamzori.
Which blood tests should I ask for if I’m always tired?
A sensible starting panel is haemoglobin and ferritin for iron, TSH for thyroid, fasting blood sugar, and vitamin D and B12 if your diet or sun exposure is limited. One blood draw usually covers the lot.
Can low iron cause tiredness even if I’m not anaemic?
Quite possibly. Ferritin shows your iron stores, and low stores can bring dragging fatigue before haemoglobin drops far enough to be called anaemia. That’s why asking for ferritin alongside haemoglobin gives a fuller picture, especially if your periods are heavy.
What are the signs of low iron?
Tiredness that drags on, pale skin inside the lower eyelid, brittle nails and odd cravings for ice are common clues. Heavy periods, pregnancy and a diet light on meat and lentils make it more likely. A blood test settles it quickly.
Can thyroid problems make you tired all the time?
Yes. An underactive thyroid slows everything down, bringing fatigue, weight gain without eating more, feeling colder than others, dry skin and thinning hair. It’s common in women over 30 and after pregnancy, and a TSH test is the usual first check.
Is constant tiredness a sign of diabetes?
It can be one of the quieter early signs, especially alongside excess thirst, frequent urination or cuts that are slow to close. If those sit with your tiredness, ask for a fasting sugar test. A result of 126 mg/dL or more is the line doctors use for diabetes.
How long should I try lifestyle fixes before seeing a doctor?
Two to three weeks of genuinely better sleep and hydration is a fair trial. If you’re still dragging after that, get blood tests rather than carrying on guessing. Don’t wait that long if you have weight loss, excess thirst or new breathlessness.
Can depression show up as tiredness?
Often, and it’s frequently missed. Low mood can appear first as exhaustion, losing interest in things you used to enjoy, poor concentration and changes in sleep or appetite. If that combination fits, raise it with a doctor as its own topic, not as general fatigue.
Do kamzori tonics or multivitamins help with tiredness?
Only if they happen to match what you’re short of, and often they don’t. A tonic won’t correct a thyroid problem, sleep debt or diabetes, and a tested iron or B12 deficiency needs a targeted dose from your doctor. Find the cause first, then fix that.
Can drinking more water fix constant tiredness?
It helps if dehydration is part of the problem, which is common when your day is mostly tea and cola. Aim for pale straw-coloured urine. It won’t fix low iron, thyroid problems or sleep debt, so treat it as one check among several.
Is it normal to feel tired during periods?
Some tiredness around a period is common. Persistent fatigue, especially with heavy bleeding, is a strong reason to check for iron deficiency rather than accepting it as normal.
Can my medicine be making me tired?
It might. Some blood pressure medicines, antihistamines and sleep aids cause daytime drowsiness. If the tiredness began around a new prescription or dose change, tell your prescriber, but don’t stop the medicine on your own.
Is tiredness in pregnancy always normal?
Some is, but persistent or unusual fatigue should be mentioned at your next antenatal visit rather than brushed off. Anaemia is common in pregnancy and easy to test for.
Does chai make tiredness worse?
Badly timed chai can, by spoiling sleep quality even when you fall asleep easily, which leaves you tired the next day and reaching for more chai. Try no caffeine after 3pm for a week and see what changes.
How many hours of sleep do I actually need?
Most adults need 7 to 9 hours. Count the time you actually fell asleep until the alarm, not the time you got into bed, for three nights. Six hours can feel fine for a week and then quietly become your new normal.
