Not every person, when going to do a survey, thinks about whether it is allowed to consume water before the survey itself. Let's look at this important issue together.
Can I drink water before giving a general blood test from a vein, sugar, hormones, biochemistry?
There are several types of blood test. The simplest are two analyzes - general and biochemical. An empty stomach - this requirement is not the only one before giving blood for analysis. To the biochemical examination of the doctor put forward their own special requirements.
Many patients, before donating blood for analysis, are asked whether it is possible to consume water before such a survey? Before donating blood, of course, doctors do not forbid drinking water, but they do not oblige it either. The liquid can be consumed as usual, but only for 30 minutes.up to the survey.
To children, doctors advise drinking fluids 2 or 3 hours before taking a blood test in the amount of 2 glasses. This requirement is resolved in the event that one-time blood sampling is required for several analyzes.
tests? Because of this, the blood becomes less viscous, therefore, getting the right amount of blood for examination will be much easier. If we talk about other liquids, such as tea, coffee, fruit juice, juice, they are allowed only after the procedure, because they can affect the chemical components of the blood itself.
In addition, before the examination is not recommended to visit the sauna with a bath, because these procedures greatly affect the body and its condition, as well as the blood. It is advisable to try to avoid the factors that can exert physical and psychological stress before donating blood: swimming in the ice-hole, hardening procedures, contrast shower.
Separately it is necessary to mention the use of alcoholic drinks. They, of course, are contraindicated. Spirits are forbidden to drink at least three days before the procedure. After all, it is during this period that an alcohol product is taken from the body.
In addition, the use of alcohol has a very strong influence on the biochemical components of the blood, and on the number of leukocytes. Therefore, if a patient drank a certain dose of alcohol before donating blood, his result would turn out to be wrong. Alcohol, usually:
- Increases lactate concentration
- Increases the presence of triacylglycerols
- Reduces the amount of sugar that is contained in the blood
The final result of blood can still be affected by medications , which the patient consumes, especially hormone drugs and antibiotics. Many of these drugs cause leukopenia and anemia. In addition, antibiotics sometimes affect blood clotting, the number of platelets and the biochemical composition of the blood. Those patients who plan to be treated with antibiotics, it is better to give blood for analysis before the course or 7 days after treatment.
tests If the patient drinks medications that need to be drunk on an empty stomach, then it is advisable to take the test before using the tablets. If it is not desirable to delay the use of tablets, then it is better not to do so. But it is necessary to warn the doctor about it when he will interpret the results.
Now consider the recommendations that must be observed before donating blood to biochemistry.
- It is forbidden to do any physical activities before the examination
- It is better to give up any type of food 12 hours before the blood donation
- Do not drink alcohol, smoke, take medication, especially antibiotics
- Exclude the use of any kind of liquid
Why doctors do not advise drinking waterbefore surrendering to biochemistry? The fact is that the liquid itself does not affect the blood test itself in any way. But those people who have hypertension, eating a lot of water on an empty stomach, can thereby increase their pressure and worsen overall well-being. This, without a doubt, will have a big impact on the result and its reliability.
analyzes? No single doctor in this area can say a single and precise answer to the question of how the liquid affects the blood content. If you are affected by this problem and you do not know how you should be, just consult in advance with your doctor who will take your blood for examination.
Is it possible to drink water before ultrasound of the abdominal cavity, kidneys, liver, FGD, FGS, EGDS of the stomach?

To make them right, you need to know whether you can use clean water and other liquids before such examinations.

- Before the survey for 1.5 hours, it is advisable not to drink any liquids

But for what reason it is undesirable to drink water before ultrasound? The answer is simple. Large consumption of liquids, as well as eating with liquor, can provoke formation of gases in the inner part of the abdominal cavity of .But this factor can be a hindrance during the survey.
Before starting an ultrasound, the patient's bowel should be completely empty. There are a lot of reasons for this. We will consider the most common of them:
- Because of water, there may be increased formation of gases.
- Because of fluid, spasms may occur.
- The human digestive system can perceive the drunk liquid as a meal and will begin to function actively because of it. This may prevent proper examination.
In the event that there is a lot of heat on the street, it is also advisable not to drink water for at least an hour. It is better to replace the drink with a moistened napkin and attach it to the skin.
After the ultrasound is also immediately better not to drink any liquids. Water should be used gradually and with small sips.
As it was said above, before the ultrasound is necessary to carefully prepare the body. During this process, the patient should consume enough water per day.
A certain amount of water can be replaced with plain tea. However, it should be remembered that before tea, tea can be drunk only light.

- You can not add sugar and natural honey to the drink
- It is not recommended to drink before ultrasound a lot of tea
- Tea is best not to eat after eating

It is not advisable to drink milk, since in this case it is equivalent to eating. The best option is a complete refusal of the liquid for the last 4 hours before the procedure.
test The children are very difficult to cope with thirst. Therefore, if the child wants to drink before the examination, it is necessary that he rinses the mouth with cold water, but in no case swallowed the liquid. Is it possible to drink water before the EGDS of the stomach?
Doctors strongly forbid to use before the survey such drinks as coffee, black tea and other similar drinks. With a very strong thirst, you can drink 100 ml of only purified non-carbonated water 3 hours before the examination. Alcoholic beverages, even low-alcohol drinks, for example, beer, are strictly forbidden to drink.

Therefore, before the examination it is allowed to drink water or weak tea in small amounts.
Before a colonoscopy, a doctor can prescribe a special diet for a patient. It should include water, low-fat broths and teas. To consume liquid is allowed during the preparatory process as much as necessary, but still want to observe the following proportions:
