Why am i so tired in the first trimester

It is common to feel tired during pregnancy. Particularly in the first trimester (0 to 13 weeks) and the last trimester (week 27 to birth). Being pregnant can be hard work, and you may be using lots of energy without even realising it.

It can be worrying to feel so tired. It is important to try and rest when you can when you are pregnant.

Causes of tiredness

It can be frustrating when you have had a good night's sleep and you wake up with no energy. It can be very hard to balance the tiredness you are feeling with working and life outside of work.

Causes of tiredness in early pregnancy may be:

  • hormonal changes, due to increased levels of the hormone progesterone
  • emotional changes - anxiety is common in early stages and will usually pass as the weeks go by

These are common symptoms in early pregnancy. They can leave you feeling exhausted, particularly if your sleep is disturbed by them.

As your body adjusts to being pregnant, it will produce more blood, and your blood pressure may drop. Your blood sugar may also be lower. These changes can make you feel more tired.

Coping with tiredness of early pregnancy

This tiredness is normal. It will pass.

Eating a healthy diet may help your energy levels. You may find that gentle exercise makes you feel good and you will have more energy.

If your feelings of anxiety are prevailing over your daily life, talk to a support person. If these feelings persist, make an appointment with your GP.

Usually, by the second trimester (weeks 14 to 26), your energy will return. Until then, rest when you can. Try to do your daily tasks in order of priority rather than trying to do everything.

Contact your GP or midwife if you feel tired and have any of the following symptoms: feeling dizzy, feeling breathless, chest pain, heart palpitations.

If you have high levels of anxiety, or if your mood is low, you may need extra support. Talk to your GP, midwife or obstetrician if these feelings persist.

Are you dragging these days? Does a nap sound fantastic right now?

Life can be exhausting at times, but especially when you’re pregnant. It’s totally normal to have some degree of fatigue right now—you are growing a human inside of you!

“Fatigue may be one of the most common first symptoms of pregnancy a woman experiences,” said Kelley Saunders, MD, an OBGYN at Banner – University Medicine Women’s Institute in Phoenix, AZ. “It is very common and quite significant in the first trimester. For many women, this improves in the second trimester and returns in the late third trimester.”

Although it’s common among pregnant women, you may still wonder why.

Why does pregnancy make you so tired?

The biggest reason: It’s hard work making a baby and it can be taxing to your body. “Your body has to adjust to maintain your health and the health of the baby inside of you,” Dr. Saunders said. “The physiologic changes and increased metabolic demand start in early pregnancy and can continue even after childbirth while breastfeeding.”

Beginning somewhere between conception and implantation, pregnancy hormones kick in – affecting your body, mood and sleep. During the first trimester, you may also experience morning sickness, frequent nighttime bathroom breaks and leg cramps, which can leave you feeling pretty tired.

Then starting around your second trimester, you may start to get a little pep in your step. You may start to feel more like yourself again. But don’t be alarmed if you are still pretty exhausted—especially if you have other children to care for. Fatigue is still possible during the second trimester.

In late pregnancy, you’ll most likely begin to feel tired again. At this point, your baby has grown quite a bit and is putting more physical demands on your body. You’re carrying around extra weight and it’s more difficult to get comfortable when you sleep. Add in leg cramps and heartburn, and sleep becomes even more elusive.

When is pregnancy exhaustion not normal?

While exhaustion is a common symptom of pregnancy, extreme fatigue is not normal and may be a sign of an underlying health condition. Dr. Saunders said you should see your health care provider if your fatigue is severe and persistent.

“A sudden onset of exhaustion and continual symptoms may be a sign of abnormal fatigue,” she said. “When fatigue is associated with fever, chest pain, difficulty breathing or an inability to perform routine daily activities, you should see your OBGYN for evaluation.”

Some of the potential underlying causes for your fatigue both during and outside of pregnancy may be due to the following:

  • Gestational diabetes: Your body may become resistant to insulin during pregnancy, which can cause you to feel very tired. Other symptoms include extreme thirst and frequent urination.
  • Anemia: A lack of iron can cause you to have an insufficient number of red blood cells to transport oxygen to your tissues and can cause you to feel tired, lightheaded and weak.
  • Infections (viral, bacterial or fungal): Being pregnant can make you more vulnerable to infections, such as urinary tract infections, which can make you fatigued.
  • Thyroid problems: Having too much or too little thyroid hormones can cause you fatigue, along with fluctuations in your weight, irritability and depression.
  • Prenatal depression: Feeling tired all the time can also be a side effect of depression. Other symptoms may include sadness, feelings of hopelessness and an inability to complete daily tasks or activities.

You are pregnant and you feel so exhausted and weak that even making a coffee sounds like climbing Mount Everest? Don’t worry, because fatigue is a completely normal condition and the majority of pregnant women go through it.

Why Am I Feeling So Tired?

Fatigue is most common in the first 12 weeks of pregnancy because this is when your body changes and starts adapting to the development phases of an embryo.

This is when the placenta, the main source of life-support for your baby, is growing. There are also other reasons why you are feeling so tired.

Firstly, the level of progesterone in your body increases while blood pressure may go down and when these two combine, they make for a partial culprit for exhaustion in the first trimester.

Secondly, if you find it difficult to sleep due to frequent toilet visits or feelings of nausea, which means not getting enough sleep, this is directly related to your tiredness.

Is There Anything I Can Do To Feel Better?

Your feelings of exhaustion are so strong that you think it is impossible to bear them any longer.

As unpleasant and endless as they seem, there are some things you can do to improve your stamina and effectiveness.

Although it is very hard to take the first steps of fighting the fatigue, be persistent as it would be greatly beneficial for you and your baby.

Here are some ways you can reduce tiredness and increase your productivity and energy:

Get Additional Rest & Sleep

First of all, try to get as much sleep as possible. Don’t let your habits prevent you from going earlier to bed if that is what your body wants.

If you’re sleepy at 8 or 9 pm, it’s completely normal to say goodnight to your family. Try not to schedule meet-ups with your friends late in the evening, especially if you’ve been feeling tired lately. You can move your social meetings to breakfasts or lunches – your friends will understand.

Also, take naps. 15-min naps can be miraculous. Although you might think 15 minutes is too short, it has the ability to reset your mind and body – and provide you with a certain amount of drive and strength.

If you are a working mommy-to-be and there are no relax rooms at your place of work, take short breaks and do nothing – lean against the back of the chair and just close your eyes.

Pay Attention To What You Are Eating

This is so important during any pregnancy – you need to pay attention to what you feed yourself and your baby by following a well balanced, nutritional diet.

Introducing certain foods into your diet will help you stay energized and get through another exhausting day.

Fruits and vegetables are rich in vitamins, minerals, and fibre, giving you a sufficient amount of natural sugars that will boost your energy levels.

Some foods that should definitely be on your diet list are red peppers, blueberries, avocado, and walnuts.

In spite of the feelings of sickness that the majority of pregnant women endure, and the fact that eating is the last word you want to hear, bear in mind that an empty stomach is the worst solution.

Eating regularly and often will make a crucial impact on how you feel.

One great way to ensure this? Make sure you always have some healthy homemade snacks on hand.

Hydrate Your Body

Apart from healthy food, adequate hydration is also paramount to keeping those first trimester feelings of exhaustion away.

Keep your body hydrated, because when you are dehydrated, the fluid loss causes a drop in your blood volume, which causes your heart to work harder to push oxygen and nutrients through your bloodstream – causing fatigue.

The recommended daily intake of water is higher in pregnant women and since most people do not drink enough fluids, what you can do to ensure that your water intake is satisfactory is to have a bottle of water always by your side and sip often instead of gulping huge amounts of water at one go.

Be Active

Stop sitting around at home watching soap operas, staring at your screen at work all day long, or using your phone mindlessly. Get outdoors and start doing some physical exercise to get your blood flowing.

Light physical activities are rejuvenating. The easiest thing you can do is to take a walk with your partner or a friend.

Whenever you have a chance, walk to a supermarket, the grocery shop, avoid driving or taking the lift whenever it is possible.

When you are at work, go out for a short walk or go to a restaurant for lunch instead of having your food delivered.

Another amazing suggestion is taking yoga classes. Prenatal yoga benefits your body in so many ways. It relieves the lower back tension and the pressure you feel in shoulders, neck, and hips. It also creates a positive impact on your nervous system – you are calmer and more relaxed. This is due to the parasympathetic mode that is on when you start breathing deeply.

Some of the benefits of yoga include maintaining an optimal immune system, better quality of sleep, and proper digestive system function.

However, if you do not feel like going out at all, there are always household chores that can keep you busy. Just be careful not to lift anything heavy or to do anything that requires intense physical activity.

Also, bear in mind that there will be days when you simply cannot lift a finger, let alone exercise. That is completely fine, embrace those days and try some mindful meditation or gratitude exercises.

The Conclusion? Enjoy It While You Can

Lastly, this is a period when you should pamper yourself as much as you can. This is when you start connecting with your baby, and nothing should come in between.

Although the first trimester can be extremely difficult and frustrating in terms of seemingly never-ending fatigue and weakness, hang in there, because it will eventually be over.

Your second trimester will come soon and that is when you are going to have more stamina and energy for everything that you had to postpone before.
