Excessive thirst and its causes

The desire is the physiological basic need of the body, manifesting itself in the drive to collect the right amount of water and fluids. Excessive thirst felt in hot weather, or in winter – when we do not provide adequate amount of water and fluids to the body – is a normal symptom of dehydration. Nevertheless, excessive thirst despite drinking water and fluids can be disturbing. 

Excessive thirst may be an abnormal condition – the so-called polydipsia. It is not a separate disease, but rather a symptom occurring in the course of various diseases. Excessive thirst is accompanied by, among others, hyperthyroidism, diabetes insipidus and diabetes. An increased desire is usually accompanied by polyuria (polyuria), i.e. excessive urinary excretion. Sometimes, excessive thirst occurs on the neurotic ground.

When the desire is excessive? 

People who feel thirsty due to dehydration and begin to drink more fluids may get the impression that they drink too much. Exceeding the norm occurs while consuming more than 5 liters per day, assuming that the person does not train much, and the atmospheric conditions do not increase the demand for liquids. 

Excessive thirst as a symptom of diabetes 

Excessive thirst usually accompanies type 1 diabetes, i.e. associated with pancreatic damage and insufficient insulin production. In this case, excessive desire is accompanied by excessive urination and weight loss. An increased feeling of thirst is a consequence of the persistence of high blood sugar levels. The body, in the face of the inability to deliver it to the cells due to the lack of enough insulin, tends to expel it with the urine. Another example of a disease that is manifested by the feeling of excessive thirst is simple diabetes insipidus. 

Straight diarrhea – vasopressin disorders 

Straight urethra is a disease manifested by excessive thirst and increased urinary excretion. This is also accompanied by the inability of the urinary system to concentrate urine. Central aorta is due to disturbances of vasopressin secretion (an anti-diuretic hormone – ADH, produced by the hypothalamus and finally released by the pituitary gland). However, renal diaphragm is caused by an abnormal reaction of the kidney coils to vasopressin. In both cases, excessive urinary excretion leads to an increased need for water, which the person feels as an excessive thirst. Hormonal disorders underlie excessive thirst also in case of hyperthyroidism. 

Excessive thirst in the course of hyperthyroidism 

Hyperthyroidism is not always manifested by excessive thirst. The clinical picture of this disease can be very diverse. Individuals experience symptoms such as palpitations, weight loss, fatigue, feeling hot, sleep disturbances, nervousness and irritability. Hyperthyroidism often takes the form of an autoimmune Graves’ disease. Due to the constantly elevated metabolic rate, the body needs more fluids. Excessive thirst may be accompanied by elevated blood calcium (hypercalcemia). A similar condition occurs in hyperparathyroidism – then the person may also feel an increased thirst. Organic reasons are not always the foundation of excessive thirst. If the person is completely healthy and yet the intake of fluids caused by excessive thirst is too high, it is necessary to check whether the problem is caused by mental disorders. 

Excessive thirst on a psychic basis 

Although this may seem unlikely, mental disorders associated with excessive stress can cause excessive thirst. By eating a lot of liquids, some people relieve stress – we are not talking about alcohol, just about mineral water, herbal teas and other beverages. Another example is the sensation of dry mouth as a symptom of neurosis or severe stress. There may be many reasons for excessive thirst, so it must not be underestimated. Sometimes it’s worth being a little hypochondriac. Inquiry about health is definitely a better attitude than ignoring the problem. 

Metabolic rate – how to turn it up and keep it at a high level?

Behind the maintenance of normal body mass is the metabolism – the general processes of synthesis and the breakdown of chemical compounds, around which many myths grew. Its pace can be increased in various ways. The metabolic rate has a huge impact on the speed of weight loss, and thus on the effectiveness of the treatment. It remains important also during the period of stabilization and maintaining the desired body mass. The most difficult thing is to maintain a high metabolic rate when the body mass decreases and the body starts saving spare tissue. At this stage, the weight loss process is further complicated due to leptin. 

The influence of leptin on metabolism 

During the weight loss, the level of leptin in the blood decreases. This hormone is responsible for the release of free fatty acids from the subcutaneous adipose tissue into the bloodstream. A low level of leptin causes the body to not burn fat, it only saves it. The hormone is secreted by the body when it does not receive food for a long time. That’s why you need to eat to lose weight. 

Eat small portions regularly 

Consumption of small portions of meals, regularly (about 4-5 every approx. 3 hours), causes that the body does not feel hunger, and thus does not switch to the so-called. tissue backup mode. Metabolic metabolism is then maintained at a high level. Regular consumption of meals also affects the maintenance of normal insulin levels, which, like leptin, has a huge impact on the weight loss process. 

Insulin and adipose tissue 

Insulin is responsible for maintaining the proper level of glucose in the blood. Too long breaks between meals make it harder to keep your appetite in check. A very unhealthy habit is eating two large meals a day, in the morning and in the afternoon. After eating a hearty meal, your blood sugar level rises significantly. Similarly happens after eating a large amount of snacks or sweets. Consequently, insulin drains glucose into the cells, and unused sugar converts to fat. In this complex process of converting sugar into fat, various chemical compounds take part, but insulin acts as an initiator. Regular consumption of low calorie meals means that fat tissue does not grow. To satisfy the appetite with a small portion of food, it is worth choosing products containing protein. 

Protein improves metabolism 

Proteins not only cause a feeling of satiety for a long time, but also lead to an increase in metabolic rate by as much as 30%. Proteins are much more difficult to absorb compared to carbohydrates (not including the fiber contained in them) and fats. The body uses more energy to convert the protein into an absorbable form. High protein intake is also important in the long term. After the end of weight loss, the muscles will work to prevent them from re-gaining weight. Muscle tissue consumes energy even when resting. For its construction and regeneration after training, proteins are needed – in the end, their primary biological function is the building function. 

Exercise in the morning 

Speaking of training, it is worth noting that exercising in the morning is beneficial for the metabolic rate. Light aerobic exercises or gymnastics cause an acceleration of the metabolic rate – it will be high for most of the day. Breakfast or at least a light snack (eg a banana or a small portion of porridge) necessarily eat before the morning workout. 

The breakfast converts the metabolism into daily mode 

The metabolic rate decreases during the night and then accelerates during the day. In order for the metabolism to get awake from sleep, one must give him a signal that the body is already active. The consumption of the first meal is such a signal. Skipping breakfast additionally causes the body to save energy. Even cheating the stomach with mineral water will not help even though its consumption also boosts the metabolic rate – in conditions of proper nutrition. 

Water – essential for life (and weight loss) 

The average daily water consumption is 1.5 liters. Skipping water in the diet leads to deterioration of well-being and health due to dehydration of the body. This also adversely affects the weight loss process. Water is needed to metabolize fats, so it is better not to ignore the recommendations of doctors and dieticians. Rins out harmful products of metabolism. Most people who train and lose weight need much more water per day than 1.5 liters. Their demand can reach up to 4 liters. 

Sleep is important 

In the case of sleep deprivation, the center of hunger is stimulated by the cerebral cortex and subcortical centers. As a result, the production of hormones that are involved in regulating the appetite is disturbed – thus the appropriate amount of sleep, as well as the bedtime affects the rate of metabolism. During sleep, the body regenerates itself, thanks to which it functions better. 

Strength training is also important 

Consuming large amounts of water is important not only because of aerobic training, which causes effective fat burning. Strength training also increases the need for fluid intake. Although its effect is not directly the process of breakdown of body fat, it favors the building of muscle tissue. Therefore, it should not be overlooked in the process of slimming. Strength exercises help to keep the metabolic rate at a later time, by causing an increase in the muscle mass of the body. Muscle, more than fatty tissue and other tissues, affect the rate of metabolism. 

Regular physical exercise 

Aerobic and strength exercises performed regularly can affect cellular metabolism by increasing its rate by up to 30%. The muscle tissue built thanks to them increases the ability to burn calories and reduce body fat. Regular physical exercise is as important as regular eating. 

Think positive! 

Negative emotions – anger, dissatisfaction, worries – do not cause that the body mass decreases. Perhaps, sometimes stress suppresses appetite to such an extent that there is a significant decrease in body weight. This may be related to eating disorders and depression. These are serious and few cases. Negative emotions associated with stressful situations cause a slowdown in metabolism. The body reacts to stress by increasing the secretion of cortisol – a hormone that slows down metabolism. What’s worse, some people have an additional phenomenon of stress. They can be mastered when you are aware of where you feel for a chocolate bar, or a packet of chips and crackers. 

Eat with taste 

After all, the diet is not about clogging up with unhealthy snacks or fiber itself. Meals should be tasty and well seasoned. If there are no contraindications to the use of spicy spices, use cayenne pepper, jalapeno peppers and other varieties of spicy peppers. Spicy spices give the dish a distinctive taste, and further reduce appetite and increase the metabolic rate. Its action results from the content of capsaicin, which leads to thermogenesis – the conversion of energy into heat. Hot pepper can speed up the metabolic rate by up to 10%. 

Consume only what accepts your body 

The slowing of metabolism may be caused by eating foods that cause food allergies. Food allergy is not always easy to recognize because non-specific symptoms may only become apparent after some time from food intake, e.g. several hours or days after ingestion of sensitizing food. Food allergy leads to disruption of the absorption process of nutrients and the inability to fully digest food. Eliminating foods that cause allergies from the diet can lead to weight loss and metabolic processes.
