“I just feel hot and tired all the time!” 

“Let’s not step out today. I don’t have any stamina!”

“The fatigue might make me faint!”

If this sounds like you, don’t feel so bad because it’s very common for pregnant women to feel this way. Though you are usually energetic and enthusiastic, this sudden lethargy can make you worry, but it is the hormonal changes that are at work.

Feeling hot and stuffy:

Hormonal changes increase the blood supply to your skin, making you feel warmer than usual and sweating more.

How to manage?

  • Wear natural, breathable fabrics like cotton 
  • Choose loose, comfortable outfits
  • At work or home, sit in well-ventilated rooms
  • Try to switch on the room fans over air-conditioners, as they allow fresh air to circulate constantly

Tiredness and Fatigue:

In the initial weeks, the nausea and throwing up leaves you feeling drained. As the body gains weight, you may feel tired easily and lack the energy or enthusiasm to do anything at one go. 

Once the pregnancy progresses, sleep patterns get impacted and the weight of the growing baby makes it challenging to sleep in any position for long. The lack of deep sleep makes you easily exhausted all the time.

How to manage?

  • Take on smaller tasks, or accomplish major tasks with small breaks in between
  • Request and accept help from family and co-workers
  • While sitting, keep your feet up on the bed / couch or on a stool
  • Take short naps at intervals, or simply lie down for a while whenever you feel too tired
  • Keep soft pillows for side support, when you sleep, and keep one between your knees while lying sideways.

Feeling dizzy or faint:

Several pregnant women say they feel dizzy or even faint, and have experienced it while getting up with a jerk, getting off the toilet seat or just turning sides swiftly. This is not a major reason to worry, as it caused by poor blood circulation and less oxygen reaching the brain as a result.

How to manage?

  • Always turn slowly while in the lying down position
  • Get up from the bed or chair gently, and have something to hold for support
  • Drink sufficient water at short intervals, to stay hydrated
  • Eat nourishing meals to keep blood sugar stable, and take your supplements regularly
  • If you’re feeling dizzy, sit or lie down and put your head between your legs until the faintness passes. If it doesn’t, lie down on your side.
  • Practice deep inhales and exhales on a daily basis

Keep your doctor and at least one family member updated each time, so that they’re able to be there for you.

CAUTION: Feeling very dizzy or faint early in the pregnancy, and also having bleeding from the vagina or experiencing nagging tummy pain, could mean that you have an ectopic pregnancy. It’s important to see a doctor right away.
