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.
When you're dehydrated, sodium levels in your blood typically rise. Your system responds by releasing more of a hormone called vasopressin, which works to help your body hang on to water. Vasopressin also can cause your blood vessels to tighten, or constrict, which makes your blood pressure rise.
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.
Something as simple as keeping yourself hydrated by drinking six to eight glasses of water every day improves blood pressure. Water makes up 73% of the human heart,¹ so no other liquid is better at controlling blood pressure.
Usually, blood pressure starts to rise a few hours before a person wakes up. It continues to rise during the day, peaking in midday. Blood pressure typically drops in the late afternoon and evening. Blood pressure is usually lower at night while sleeping.
Your body's fluid levels affect how well your kidneys can filter out toxins, and also have a big impact on blood pressure. If you haven't taken in enough for your body to keep things running well, your brain will let you know by triggering a thirst response, Dr. Moreno says.
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.
For instance, eating a particularly salty or spicy snack or meal just before bed can cause thirst that's temporary, but intense — potentially intense enough to wake you up. Additionally, alcohol and caffeine can dehydrate your mouth, so it's best to limit both before going to bed to avoid dry mouth.
In fact, heart failure syndrome itself and its treatment also contribute to the thirst response. In other words, it is normal to feel thirsty when you have heart failure. At the same time, it is very important to prevent dehydration because being dehydrated means your heart has to work harder to pump blood.
Can not drinking enough water cause high blood pressure? Yes, not drinking enough water leads to dehydration, which has been shown to increase blood pressure.
Certain Health Disorders
Dry mouth could also be indicative of a health condition. Those with HIV, diabetes, anemia, high blood pressure, or hypertension are more likely to deal with dry mouth.
Dehydration: Dehydration can sometimes cause blood pressure to drop. However, dehydration does not always cause low blood pressure but may cause other symptoms such as weakness, dizziness and fatigue.
Transparent and lacking in color
Transparent, colorless urine could also be a sign of some other health disorders, including diabetes and kidney disease, or from taking diuretic medication.
Pale or transparent yellow urine
Diabetes insipidus is a condition in which the body produces excess urine. It can cause people to pass large quantities of light-colored urine every time they urinate. It can also cause people to feel very thirsty, leading them to drink fluids frequently.
Thyroid problems
When the gland produces too much or too little hormone it can spur a variety of nonspecific symptoms, including abnormally heavy periods, anxiety, feeling hot, and dry mouth-all of which can lead to increased thirst.
The best way to determine if you have type 1 diabetes is a blood test. There are different methods such as an A1C test, a random blood sugar test, or a fasting blood sugar test. They are all effective and your doctor can help determine what's appropriate for you.
Call 911 or emergency medical services if your blood pressure is 180/120 mm Hg or greater and you have chest pain, shortness of breath, or symptoms of stroke. Stroke symptoms include numbness or tingling, trouble speaking, or changes in vision.
Walking lowers systolic blood pressure by 4.11 mm Hg (95% CI, 3.01 to 5.22 mm Hg). It lowers diastolic blood pressure by 1.79 mm Hg (95% CI, 1.07 to 2.51 mm Hg) and resting heart rate by 2.76 beats per minute (bpm; 95% CI, 0.95 to 4.57 bpm).
