The typical symptoms of diabetes are three polydipsia and one hypochondriac. And one of them, polyhydration and polyuria, is thought by some patients to have a possible causal link with diabetes. In order to cut this connection, so they often hold a grudge and are usually afraid to drink water. Even if they are thirsty, or in the summer heat, they deliberately limit the amount of water they drink. This is a big misunderstanding and extremely detrimental to patients. We believe that; water is the source of life. The human body accounts for 70% of the water, normal people should drink water properly. As a diabetic patient not only should not restrain drinking water, but also replenish more water than normal people. This is because diabetic patients can not be used by the body due to the relative lack of insulin secretion, so that the blood sugar stays in the body causing hyperglycemia. The blood concentrates and is hypertonic, producing osmotic diuresis, so polyuria symptoms occur. Water loss, in turn, leads to dehydration, creating thirst and the need for timely hydration. So, what is the best water solution to take? Let’s take a look at the drinks on the market:Carbonated drinks are composed of sugar, carbonic acid, flavoring, artificial coloring and other additives, which are obviously not good for diabetics. Beer is brewed with barley malt p hops p water as the main raw material o by the yeast fermentation effect is full of carbon dioxide low alcoholic liquor. Most international beers now have auxiliary ingredients added, and some countries specify that the total amount of auxiliary ingredients does not exceed 50% of the amount of malt. The alcohol content is around 3 to 6°C and may also induce serious consequences of hypoglycemia in patients using sulfonylureas or insulin. So it is also not suitable for diabetic patients to use it as a regular drink. And chilled beverages have adverse effects on the gastrointestinal tract, especially since most commercially available beverages are sugary, and various additives and preservatives are not suitable for diabetics. Milk and soy milk both contain protein and other nutrients, and can also be supplemented with calcium, so it is advocated that diabetics should be properly supplemented with milk and soy milk. Tea is a healthy drink, containing theophylline, vitamins, tea polyphenols and trace elements and other substances. It has a variety of effects such as brain enhancement and refreshment, diuretic and antihypertensive, weight loss and fat removal. Properly consumed, it is beneficial to the human body and will not affect the control of blood sugar in diabetic patients. Of course, before going to bed and when taking medication, it is best not to drink tea, so as not to affect sleep and drug effects. Moreover, as hydration, due to the diuretic effect, then it is not good for the patient. Through the above analysis, we believe that plain water and mineral water are the first choice for hydration. Diabetic patients can take in unlimited amounts. In fact, it is possible to drink water at any time. In order to drink water really effectively, the best way is to finish a glass of water of about 200 – 300 ml in one gulp, so that the body can absorb and use it, rather than just take two sips. Also, you don’t have to wait until you’re thirsty to think about drinking. That does not necessarily have the effect of quenching thirst, but also can not achieve the effect of hydration. The best time to drink water is on an empty stomach, when the water is absorbed directly in the digestive tract, to play the best effect.
