Does Drinking Too Little Water Affect Blood Test Results Before Chemotherapy?
Does drinking too little water affect blood test results before chemotherapy? For cancer patients about to undergo chemotherapy, one important step before treatment is a blood test, to assess whether the body is ready. Many people focus on diet, rest, or protein supplementation, but there is another factor that is often overlooked: drinking water. A common question is: does drinking too little water affect blood values? Can it really cause blood values to fail? How much water should you drink before a blood test?
Why is a blood test needed before chemotherapy? Before administering chemotherapy, doctors need to check the body's readiness, especially
- White blood cells
- Red blood cells
- Platelets
- Liver function
- Kidney function
If some values are too low or abnormal, it may be necessary to
- Postpone chemotherapy
- Adjust medication
- Give a blood transfusion
- Give blood cell stimulating drugs
How is water related to the blood system? Many people think that blood and water are separate matters, but in fact they are closely related, because blood is made up of
- Plasma (water in the blood) ~55%
- Blood cells ~45%
Therefore, drinking water directly affects
- Blood concentration
- Circulation
- Blood test results
Does drinking too little water affect blood test results? The answer is yes, it truly can, especially in cancer patients. Possible effects include
1. Hemoconcentration When the body is dehydrated, plasma decreases → the blood becomes concentrated
The result is
- Some values appear falsely high
- Some values become distorted
2. The kidneys have to work harder Water helps flush out waste products and chemotherapy drugs; drinking too little water can cause
- Kidney values to worsen
- A risk of postponed chemotherapy
3. Low blood pressure, dizziness which weakens the body
4. Slower recovery after chemotherapy because waste products accumulate
Which blood values are affected by drinking too little water?
- Kidney values (BUN / Creatinine) can rise if dehydrated
- Red blood cell concentration appears high, but this is a result of concentrated blood
- Electrolytes become imbalanced
Does drinking too little water mean chemotherapy can't happen at all? Directly, it may not be the main cause, but it is a contributing factor that can lead to
- Kidney values not passing
- The body not being ready
- A risk of complications
Why do cancer patients drink too little water?
- Nausea, not wanting to drink
- Feeling full easily, even a small amount feels like too much
- Difficulty swallowing
- Fear of needing the bathroom frequently
How much water should you drink before a blood test On average, 30–35 mL per 1 kg of body weight per day, for example, a body weight of 50 kg → 1,500 mL or more
How many days in advance should you start drinking more water? At least 3–5 days before the test, to allow the body to rebalance
Techniques for drinking water for those who find it difficult
- Sip frequently, rather than drinking a large amount at once
- Use a straw to make it easier to drink
- Mix with diluted fruit juice
- Drink warm water to reduce nausea
Beverages that can help replace water
- Soup broth
- Coconut water
- Smoothies
- Milk
Warning signs that the body is dehydrated
- Dry mouth
- Dark-colored urine
- Dizziness
- Fatigue
- Dry skin
Is drinking too much water dangerous? It can be dangerous if you have
- Kidney disease
- Heart failure
You should consult a doctor
Besides water, what else needs to be added before a blood test? Although water is important, it is not enough on its own. What must also be included is
- Protein
- Energy
- Vitamins
Why is protein important before a blood test? Because it is used to build
- Red blood cells
- White blood cells
- Platelets
If lacking → blood values recover slowly

- Experience nausea
