Excessive Thirst During Pregnancy- Causes & Symptoms

Pregnancy is a beautiful phase that marks the beginning of motherhood. During pregnancy a woman’s body undergoes huge transformations, few being visible while few go unnoticed only to be felt by the woman. Few symptoms don’t concern but few can be alarming if they get worse with time. In this article, we will highlight the causes and symptoms of excessive thirst during pregnancy which is usually not a concern but in rare cases can be a symptom of gestational diabetes.

Dry mouth is a common pregnancy symptom. This is due, in part, to the fact that you need a lot more water while pregnant since it aids in the development of your baby.

Another explanation is that hormonal changes can have an impact on your oral health. Besides dry mouth, you may develop gingivitis and lose teeth while you are pregnant.

The more water you drink, the better your kidneys will be able to cleanse your body of the excess waste products produced by the fetus.

You also need more fluids because there is a 40-45% increase in your blood volume during pregnancy. Furthermore, your baby requires fluids to fill his or her pool of water (the amniotic sac).

Being thirsty and urinating more than normal is a common pregnancy symptom that is not a cause of concern. These issues can be a symptom of gestational diabetes (a category of diabetes that affects pregnant women). If you are at risk, you should be checked for this as part of your prenatal care.

Excessive Thirst During Pregnancy- Causes

Dehydration: During pregnancy, most women notice an increase in the frequency of their urination. You will most likely feel thirstier in the early stages of pregnancy since your body is encouraging you to drink extra fluids for you and your baby. Your body requires extra fluids to assist in the elimination of waste generated by natural functions as well as waste generated by your baby. Some women, particularly those who live in hotter regions, may experience thirst as a result of increased sweating.

Low blood pressure: Low blood pressure can make you feel thirsty and dehydrated during your pregnancy and if you miss drinking sufficient water, you might also feel faint, have a hazy vision, dizziness, nausea, and irregular breathing

Certain food and drinks: Eating salty or spicy food can make you feel thirsty. If you feel thirsty after taking junk food then try to avoid it. Consuming caffeinated beverages can also make you feel dehydrated and thirsty. 

Issues with sleeping: Pregnancy can cause disrupted sleep patterns, sleep apnea as well as snoring. Snoring can be problematic if it leads to feeling tired the whole day.

Oral thrush: Overgrowth of Candida albicans can make you feel thirsty because it causes a dry, cottony texture and soreness in your mouth. 

Frequent urination: The fetus grows, and the uterus begins to expand from the second trimester leading to pressure on the bladder that makes you want to urinate, leaving you thirsty.

Diabetes insipidus: Diabetes insipidus rarely occurs during pregnancy which leads to extra loss of fluid from the body and thus makes you feel thirsty. The loss of electrolytes like calcium and sodium will also make you feel tired due to dehydration. 

Gestational diabetes: It can be one of the leading causes of dry mouth and thirst during pregnancy and can cause high blood sugar level that usually goes away after you give birth. More than the usual amount of insulin is required during pregnancy and when the body can’t make that extra insulin, gestational diabetes occurs which can cause problems for the mother and the baby. Gestational diabetes can be managed with a healthy diet, exercise, and also with certain medication or insulin.

A woman suffering from gestational diabetes has no or moderate symptoms. It can be found in this scenario through a test offered to all pregnant women.

Fatigue, excessive thirst, and frequent urination can be viable signs of gestational diabetes which can be confirmed by the test.

Consult your doctor if home remedies do not help with your dry mouth or if you have other signs and symptoms of diseases such as gestational diabetes. An early diagnosis and treatment will avoid future mishaps.
