Sometimes, pregnant or not, you may have the urge to drink a lot of water through the day. While most people may feel that drinking up to eight glasses of water in a day is enough, as an expecting mom you may need a tad more. Feeling excessively thirsty at all times, especially when you are pregnant, may have more to it than meets the eye, or indeed than quenches the thirst.

If you have begun to feel excessively thirsty while pregnant and find yourself reaching for water frequently, reading our post could be a good idea. Here we talk about excessive thirst during pregnancy, and whether it is part of pregnancy or something that you should share with your doctor.

What Do You Mean By Excessive Thirst During Pregnancy?

Severe thirst during pregnancy, as it sounds, is a situation where you may be drinking water all the time, but it may never seem enough. When you are pregnant, your body does need more fluids. Consequently, it can often become difficult to understand if your excessive thirst in pregnancy is a part of your ongoing pregnancy, or whether there is an underlying cause that needs medical attention.

Symptoms Of Excessive Thirst During Pregnancy:

Feeling excessively thirsty is one of the most prominent signs of excessive thirst while you are expecting. Here, we list some other symptoms:

  • Having a feeling of dryness in the mouth
  • Need to urinate all the time or more frequently
  • Swelling in the hands, feet and ankles

Causes Of Excessive Thirst During Pregnancy:

Apart from not having enough water, here are some reasons that could lead to an increase in your thirst levels while you are pregnant:

1. Not Hydrated Enough:

  • Whether you are in your first trimester or any other stage during your pregnancy, it is always possible that you will experience the need to urinate more. In the earlier part of your pregnancy, you will feel thirstier than usual as your body will tell you to take in more fluids for you and your unborn baby’s health.
  • The fluids in your body will help to remove any waste from within, and it also includes the waste that your unborn baby will produce while inside your womb.
  • The amniotic sac around your unborn baby will keep your little one protected, but you need to have enough fluids so that the amniotic sac is full.
  • If you sweat a lot at night, or if your body temperature is a little higher than what it was before you got pregnant, you feel thirstier than usual.

2. Low Blood Pressure:

  • Around the time you are about 24 weeks pregnant, it is common to experience a dip in blood pressure levels.
  • When your blood pressure drops, your heart will have to work harder and to pump more blood. As a result, you may experience an increase in thirst.
  • If you do have low levels of blood pressure, you will also experience some other symptoms in addition to an increase in thirst levels. Some common symptoms of low blood pressure are feeling dizzy and light headed, skin turning cold to the touch, nausea, blurry vision, an increase in fatigue, breathing too fast or shallow breathing and in some cases, even fainting.

3. Increase In Blood Volume:

  • When you are pregnant, your body also goes through an increase in the volume, or amount of blood, which is quite natural.
  • During pregnancy, the volume of blood in your body can increase by up to 40 percent. To replenish this additional need of blood, your body will need more water. Hence, you may notice that you feel an increase in your thirst levels while you are pregnant.
  • Your body needs all the extra amount of blood during pregnancy so that it can provide your unborn baby with all the required amount of nutrients and oxygen. It will also help new cells in your unborn baby to develop the way they should.

4. Your Food Or Drink:

  • Sometimes, you may not experience an increase in your thirst levels but may only experience the same if you recently had something to eat or drink.
  • When you eat salty foods or foods that have a high amount of spices, it can make you feel thirsty all of a sudden.
  • If you do experience an excessive need to drink water after having something to eat, make a note of it and avoid it for some time.

When Does It Become A Cause For Concern?

While you are pregnant, there are so many changes going on both inside and outside your body, that it can be overwhelming to say the least. In some cases, the need to drink too much water can be a normal sign that your pregnancy is growing the way it should. However, it is important to talk to your doctor about this, as your medical team will be the best judge of whether you need to go for any tests or whether it is normal. Here are a few situations when you should speak to your doctor and talk about your excessive thirst levels:

  • It is possible to feel an increase in your thirst levels in the earlier part of your pregnancy, as well as in the latter part.
  • When you reach the later part of your pregnancy, you have to be very careful and take a proper look at your symptoms. If you do notice an increase in your thirst levels, it could be because your uterus, which will grow to a considerable size now, puts more pressure on your bladder. You will feel the need to urinate even more frequently than what you felt in the earlier part of your pregnancy. When your body loses so much fluid so rapidly through such frequent passing of urine, you will need more fluids to replenish the lost ones. So, you will feel thirstier than normal.
  • The above may also point towards the start of gestational diabetes, especially if you also experience a feeling of being tired all the time, in addition to passing urine too often.
  • If your doctor does suspect you may have gestational diabetes, you will be asked to go for a blood sugar test, also known as a glucose tolerance test. In case your test results show that your numbers are higher than 140 mg/DL, you may be at risk of developing gestational diabetes.
  • It is very common to develop gestational diabetes, because when you are pregnant, your body has to produce more insulin to properly meet the many changes that it is going through. If your body is not able to produce the right amount of insulin that it needs at this time, you have a higher chance of developing gestational diabetes.
  • If you had gestational diabetes in an earlier pregnancy, your chances of developing it again during the recent pregnancy are also high as compared to those who did not have it earlier. Make sure you tell your doctor about your previous history of gestational diabetes.
