What Are the Symptoms of Hot Flashes During Pregnancy?

Sometimes, the feeling of increased body heat may be misunderstood as fever. Remember, fever raises your body temperature, hot flashes do not. Let’s have a look at the symptoms of hot flashes:

  • The sudden feeling of warmth, increased heat of the body, particularly at face, neck and chest characterize hot flash.
  • The face appears flushed or blushed (red).
  • Sweating
  • Chills
  • Increased heart beat

The hotness may linger from a couple of seconds to minutes. However, if you have a fever or your body temperature rises above 100 F, do call your doctor as fever could be a sign of an infection.

What Causes Hot Flashes During Pregnancy?

The primary causes behind hot flashes are outlined below. Knowing what may be your case, you can tame the occurrence of hot flashes:

1. Hormonal Play

There are a lot of hormonal fluctuations in the body during pregnancy. There is a sudden surge or drop in hormones, which leads to the feeling of increased heat in the body.

2. Dehydration

Your body needs water to regulate temperature. If there is inadequate water supply, then this mechanism is disrupted leaving your body hotter than usual.

3. Increased Metabolism

The body metabolism generally increases during pregnancy leading to increased core body temperature. The higher the metabolism, the greater the body temperature.

4. Overweight

It’s alright to give in to your cravings, but remember extra fat won’t do any good and may contribute to hot flashes. The excess fat stored in the body dissipates its own heat.

How Can I Know If I Am Getting Hot Flashes or Fever?

Hot flashes are not harmful for your baby, but fever may jeopardize the situation. Below are a few markers to help you diagnose hot flashes:

  • It does not stay for long, it’s usually a fleeting sensation.
  • When in doubt, do measure temperature using a thermometer. If the temperature is above 100 F, it’s time to call the doctor.

Although hot flashes are common among pregnant women, make sure you mention this to your obstetrician. It is just to confirm that there are no underlying medical conditions such as high blood pressure, endocrine-related disorders and fever that are causing hot flashes.

Hot Flashes in Pregnancy – Boy or Girl?

Folklore has it that hot flashes during pregnancy can be indicative of the gender of the unborn baby. Just like they say that if you are carrying low, it’s a boy and carrying high and wider it is a girl.

However, it needs to be noted that hot flashes are not a sign of your baby’s gender, they are just hormonal triggers during your pregnancy. Science does not claim any such finding so rest assured, hot flashes are no more than another pregnancy (and post-pregnancy) hormonal condition.

Some mums may continue to experience hot flashes even after pregnancy, it’s usually nothing to worry about. You will be alright once your hormones have settled down. Just keep your calm, get plenty of rest and relax yourself. Most of the problems will be solved when you stop thinking too much.
