Here, we will talk about whether this phenomenon is normal and whether you need to tell your doctor about it or not. Read this article to know about increased thirst in early pregnancy.

Is it Normal to Feel Extremely Thirsty During Pregnancy?

For most women, increased thirst during pregnancy is entirely normal. Your body simply needs more fluids to function properly. Also, you’re drinking water not only for you but for the little one inside you as well. However, it is understandable for you to wonder whether it is a normal part of pregnancy or due to some underlying medical cause. Let’s explore more below.

Causes of Excessive Thirst During Pregnancy

Here are some factors that can lead to you feeling excessively thirsty during pregnancy:

1. Low Blood Pressure

Around the time when you are 24 weeks pregnant, it is normal to experience a dip in blood pressure. When this happens, your heart has to work more to pump more blood. This will contribute to increased thirst. There are also a few other symptoms you may experience with this dip in blood pressure, including feeling faint, nausea, dizziness, blurry vision, and breathing abnormalities.

2. Increase in Blood Volume

Pregnancy can increase the volume of blood in your body by about 40 percent. Your body will need this extra amount of blood to provide your baby with nutrients and oxygen and ensure proper cell development. To replenish this additional need for blood, your body will need more water, thereby, increasing thirst levels.

3. Certain Foods or Drinks

When you eat salty food or food with lots of spices, you may become thirsty all of a sudden. If you find yourself feeling excessively thirsty after eating or drinking certain things, it’s best to avoid them for some time.

4. Not Being Hydrated Enough

Most women often find themselves feeling the need to pee more often during pregnancy. You will likely feel more thirsty in the earlier stages of pregnancy, as your body is telling you to take in more fluids for yourself and your baby. As your baby grows in your womb, the amniotic sac (fluid-filled chamber protecting your baby) grows larger as well. Your body needs more fluids to help rid itself of waste produced from your normal functions, as well as waste being produced by your baby. Some women, especially ones who live in warmer climates, will find that their thirst is due to more sweating.

5. Pressure on the Bladder

As the baby continues to develop and grow, your womb will expand and start to press down on your bladder, causing the urge to urinate more frequently and drink more fluids. As you expel more fluids, your thirst will increase.

6. Increase in Kidney Needs

From calorie intake to better sleep, your body amps up everything it needs during pregnancy. Your kidneys might simply need more water to deal with the calorie intake and supplements you might be taking, leading to excessive thirst.

7. Hormone Increase

Hormones like estrogen may increase during pregnancy, which causes excessive thirst. You might wonder ‘why am I so thirsty when pregnant?’ This is normal, so make sure to stay hydrated.

When You Should Be Concerned About Excessive Thirst During Pregnancy?

It is best to talk to your doctor to ensure that excessive thirst during pregnancy is due to normal reasons and not any cause for concern. When you reach later stages of pregnancy, you should be very careful while analysing your symptoms.

However, the above may also point to start of gestational diabetes, especially if you feel constant fatigue along with urinating frequently.

The doctor may insist on a blood sugar test, also known as a glucose tolerance test if she suspects that you have gestational diabetes. If your numbers are higher than 140mg/DL, you may be at risk of developing gestational diabetes. Gestational diabetes is very common during pregnancy, as when you are pregnant, your body has to produce more insulin to keep up with all the changes. If your body is not able to produce the right amount of insulin required, you may develop gestational diabetes.

If you had gestational diabetes during an earlier pregnancy, the chances of developing it in your current pregnancy are higher. Make sure you tell your doctor about previous cases of gestational diabetes, so the appropriate measures can be taken.

  • A feeling of dryness in the mouth.
  • Feeling excessively tired, even if you have slept well.
  • Impaired vision.
  • Infections that happen too often, like thrush.
