Excessive thirst can sometimes be a side effect of certain types of medication, including lithium, certain antipsychotics and diuretics (water tablets). If you think a particular medicine is causing your thirst, it may be possible to change to a different medicine or reduce your dose.
Dehydration. Dehydration means your body doesn't have enough water to carry out normal tasks, and thirst is the main symptom. It can happen for a lot of reasons, such as exercise, diarrhea, vomiting, and too much sweating.
The urge to drink too much may be the result of a physical or emotional disease. Excessive thirst may be a symptom of high blood sugar (hyperglycemia), which may be due to diabetes. Excessive thirst is a common symptom. It is often the reaction to fluid loss during exercise or to eating salty foods.
Angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs) are drugs that doctors frequently prescribe for people with hypertension. One of the side effects of these drugs is dehydration.
Your body needs a certain amount of water for your salivary glands to produce enough spit (saliva). If your salivary glands don't produce enough saliva, it can result in dry mouth. Other potential causes of extreme thirst at night include: Medications you're taking.
Deficiencies in Vitamin A or riboflavin can also cause dry mouth. While both these conditions are rare, they are real and serious, and a medical professional should treat them. Read on to find out if you're experiencing the symptoms of dry mouth.
Dry mouth can be a side effect of medical conditions, including Sjögren's syndrome, HIV/AIDS, Alzheimer's disease, diabetes, anemia, cystic fibrosis, rheumatoid arthritis, hypertension, Parkinson's disease, stroke, and mumps.
Drugs for conditions including cancer, high blood pressure, and type 2 diabetes may cause a water imbalance. If you're taking any of these meds, it's crucial to watch for signs you're dehydrated. Thirsty much?
BLOOD PRESSURE MEDICATION These medicines often control blood pressure by having an effect on the distribution of electrolytes, salts and water balance in the body. This can result in increased fluid loss from the body.
Medications can also affect your level of hydration. Certain antihistamines, blood pressure medicines, laxatives, diuretics and chemotherapies can cause dehydration.
If you feel thirsty all the time, it could be a sign of diabetes – particularly if you also have other symptoms such as needing to urinate frequently, extreme tiredness (fatigue) and unexplained weight loss. Diabetes is a lifelong condition that makes it difficult to control the level of sugar (glucose) in your blood.
We all need to drink water — typically more than we realize. So, what if you drink loads of water each day but are still feeling thirsty and dehydrated? It can be a sign that something else is going on. Factors like your medication, how much you sweat and if you're sick can affect your levels of hydration.
It's also likely that you'll feel thirsty all the time and have a "dry" feeling that's always present, no matter how much water you drink. If you need to pee regularly and always feel thirsty, your sleeping patterns and daily activities may be disrupted.
Thyroid problems
The thyroid gland weighs less than one ounce, and is found on the front side of your neck, in front of your voice box [6]. Although it is one of the lesser known organs, your thyroid is incredibly important for day-to-day body function. Excessive thirst could be a sign that your thyroid is overactive.
If your thirst seems greater than it should be and persists even after a tall glass of water, there may be an underlying medical situation. If you have diabetes insipidus, for example, your body may be producing large amounts of urine, especially in people who also have high blood pressure.
“Drinking plain water can still leave you thirsty sometimes due to loss of sodium and potassium through sweating, causing an electrolyte imbalance,” she said.
Most of the time, blood pressure medicines do not cause side effects. Some people have mild side effects, including dizziness, headaches, swelling in the legs or feet, or stomach problems.
Many diseases -- such as diabetes, cystic fibrosis, and kidney disease -- increase dehydration risk and the need for fluids. For example, people with uncontrolled diabetes urinate frequently. Some medications can also cause a person to urinate or sweat more than normal.
Heart medication and drugs prescribed to lower your blood pressure, such as enalapril and nifedipine, may have a pronounced drying effect on the mouth.
Safe medications to use include methyldopa and potentially some diuretics and beta-blockers, including labetalol.
Excessive thirst can be a common symptom or condition in cases of high blood pressure and it can be the reaction to excessive fluid loss during exercise or when one eats salty food.
What can cause a dry mouth? A dry mouth can occur when the salivary glands in your mouth don't produce enough saliva. This is often the result of dehydration, which means you don't have enough fluid in your body to produce the saliva you need.
Medical conditions: Dry mouth can be a sign of a more serious condition, such as diabetes, Alzheimer's disease, stroke and Sjogren's syndrome. Sjogren's syndrome (SHOW-grins) is an autoimmune disease that causes the body to attack the glands that produce moisture.
Sjögren syndrome is a chronic autoimmune disorder. It causes your white blood cells to fight the glands that produce your body's moisture. It affects more women than men.
