A popular belief is that if we are very thirsty, we are now seriously dehydrated. However, according to experts, thirst is far from being the only symptom of dehydration . The body also gives us other symptoms that it needs water, some of which appear earlier than the feeling of a strong thirst . It is good to recognize them in time to maintain the fine balance of fluid in the body.
In the conditions of dehydration, the nerve impulses sent from the brain to the muscles do not move properly, and the most natural reaction of the muscles in this case is the excessive constriction, i. appearance of cramp or cramp. Such situations are very common in physical stresses when we lose more fluids, but can also occur at rest when water is inadequate.
Increased hunger for sugar products
One of the first organs that senses dehydration is the liver. Under conditions of insufficient fluid supply, it slows down its function and does not release enough reserve glycogen in the blood. It quickly removes blood sugar and generates a feeling of hunger, and sugar products appear to be the most attractive source of glucose in such conditions. Thus, increased appetite for jam may also be considered as a symptom of dehydration.
normal fluid balance in the body has a role in maintaining blood pressure. Among the first consequences of dehydration is the rapid fall in blood pressure , resulting in the onset of symptoms such as dizziness and vertigo. Therefore drinking plenty of water is one of the leading first aid measures in such situations. The relationship between dehydration and dizziness in this case is explained by the influence of low blood pressure on the operation of the vestibular apparatus.
Problems with the excretory system
Dehydration has a negative impact on the entire system. On the one hand, it drastically reduces the amount of urinary urine, and on the other – it can lead to serious constipation . In both cases the reason is that the body is trying to keep as much fluid in the body as possible to compensate for their reduced intake.
It is important to note that dangerous dehydration threatens us not only in the hottest heat. In such conditions, we often think of drinking water and getting more fluids. More dangerous, however, is in the cooler time when studies show that over 50% of people may not even think they have a recommended minimum of 1.5-2 liters of water per day .
Dehydration reduces the functionality of each level of organization of our body – cellular, systemic, organ. These symptoms may occur at any age . A timely response to any of these dehydration symptoms may help prevent possible complications.
