Why do patients with diabetes experience increased thirst and extreme hunger?

Why does diabetes make you thirsty? The part of our brain that tells us we are thirsty is called the hypothalamus. Both the brain and kidneys can signal the adaptive ‘thirst’ response telling us we are thirsty. Paying attention to excessive thirst is important because it could be one of the warning signs of diabetes. Excessive thirst & hyperglycemia Two of the most common symptoms associated with diabetes (type 1 & type 2) are increased thirst and increased urine production. The kidneys are a common factor between these two symptoms. Excessive thirst may be a symptom of high blood sugar (hyperglycemia). It’s important to be able to recognize any imbalance in thirst or urine production. It’s the function of the kidneys and other organs to help filter out impurities. When there is a buildup of sugar in the bloodstream, our organs, especially the kidneys may become ‘overworked.’ Excess sugar becomes a burden directly on the kidneys as they work to keep up with the volume of excess sugar. The impact of excess blood sugar causes a reaction of hydration which notifies our brain that more fluids are needed causing extreme thirst. Early detection prevents organ damage Not only the kidneys but over time if diabetes goes undiagnosed or untreated the pancreas can also be permanently damaged. If you are noticing extreme thirst, talk with your healthcare provider. There are tests that can be done to determine its cause. Recognizing symptoms like extreme thirst and urine production and getting tested for diabetes, can help prevent organ damage. Typical symptoms of diabetes include:

If someone is experiencing excessive thirst and frequent urination, they should see a doctor. In this article, we describe the connection between excessive thirst and diabetes, as well as the different types of diabetes that can cause this symptom.

What is excessive thirst? (adsbygoogle = window.adsbygoogle || []).push({});Age, lifestyle, and activity levels can contribute to how much a person drinks. According to theCenters for Disease Control and Prevention (CDC), there are currently no guidelines about how much water a person should drink each day. In 2004, theInstitute of Medicineestimated an adequate daily water intake as 3.7 liters for males and 2.7 liters for females. These amounts included water from all the drinks and foods in a person’s diet. According to theNational Health and Nutrition Examination Survey, 2009–2012, males in the United States tend to consume 3.46 liters of water per day, while females in the country typically consume 2.74 liters per day. These figures also included water from all dietary sources. However, from day to day, a person may feel more or less thirsty for a variety of reasons. Spending time in the sun or being especially active, for example, can contribute to thirst. Diabetes that causes excessive thirstDifferent types of diabetes can cause excessive thirst. Diabetes mellitusThe term “diabetes mellitus”includesdiabetes types 1 and 2. A person with type 1 diabetes is unable to produce insulin. Someone with type 2 diabetes is able to produce insulin, but their body is unable to use it effectively to help glucose enter cells. In either case, glucose from digested food remains in the bloodstream. As the authors of a2014 articlenote, the kidneys excrete some excess glucose through urine. As the glucose draws water into the urine, the body loses more fluid than it should. This results in the person becoming extra thirsty. Gestational diabetesGestational diabetes occurs during pregnancy. Just as in a person with diabetes mellitus, in a woman with gestational diabetes, insulin resistance canlead tohyperglycemia. Diabetes insipidusDiabetes insipidus is arare conditionthat involves the kidneys passing an unusually high amount of urine, which is diluted and odorless. Typically, the kidneys pass about1–2 quartsof urine a day. In someone with diabetes insipidus, the kidneys can pass3–20 quartsa day. This results in the person being excessively thirsty. Unlike a person with diabetes mellitus, someone with diabetes insipidus hasnormalblood glucose levels. However, their kidneys are unable to balance the amount of fluid in the body. This can happen for a number of reasons, including:
The factors above can disrupt the function of the hormone vasopressin. This hormone works with the brain and kidneys to help regulate fluids in the body. Other symptoms of diabetesSomeothersymptoms of diabetes include:
Treatment and managementThe right approach to diabetes depends on the type, and a doctor can recommend the best course of action. Type 1 diabetesPeople with type 1 diabetes need to take insulin. A doctor may recommend:
A person with type 1 diabetes also monitors their blood glucose levels with a device called a meter. They use a lancet to take a drop of blood and apply it to a test strip. The test results can help the person make decisions about their diet and medication routine. Type 2 diabetesSome people with type 2 diabetes are able to manage the condition through diet and exercise. Others also benefit from taking medication, such as metformin (Glucophage), which comes as tablets or a liquid. Gestational diabetesThe doctor will focus on keeping blood glucose levels in check. They may recommend special meal plans, scheduled activities, insulin injections, or a combination. A woman with this condition may need to monitor her blood glucose levels every day throughout the pregnancy. Diabetes insipidusFor someone with diabetes insipidus, the primary treatment is drinking enough liquid to prevent dehydration. A doctor may refer the person to a specialist for testing or treatment. This might be a nephrologist, who specializes in kidney-related conditions, or an endocrinologist, who specializes in hormone disorders. Diagnosis If a person has symptoms of diabetes, a doctor may perform blood tests to make a diagnosis. A doctor may also want to test infants or young adults with family histories of type 1 diabetes, as well as people with risk factors for diabetes, including overweight or obesity. Healthcare professionals should test pregnant women for gestational diabetes between24 and 28 weeksof gestation. To check for transient diabetes insipidus in pregnancy, a doctor may perform awater deprivation test. Lifestyle tipsTo help manage diabetes or better understand the course of the disease, a person can:
Overall, having a healthful diet and lifestyle can help prevent some forms of diabetes. This can involve:
When to see a doctorIf someone is excessively thirsty and has dry mouth, they should see a doctor. A person should also see a doctor if they are urinating more often than usual. People with diabetes should report any new symptoms or unusual blood glucose readings to their doctor or another member of their diabetes management team. Because diabetes can cause further health issues, it is important for people with the disease to routinely visit a doctor.
For people with diabetes insipidus, the main complication is dehydration. Symptoms of dehydration include:
A person with any of these symptoms should receive medical attention immediately. Summary Anyone who experiences excessive thirst should see a doctor, who may check for diabetes. A person may also be dealing with dry mouth and frequent urination. People with diabetes need to manage the condition carefully and report any new symptoms to their doctor or diabetes team. A family history of diabetes or ongoing health issues, such as obesity, can increase the risk of developing the disease. A person can often limit their risk by maintaining a healthful diet and lifestyle. |
