Why You Should Not Ignore Tiredness during Your Period

31 August 2017

Many women suffer from menorrhagia, which is more commonly known as heavy periods. Around 1 in 3 women will seek treatment for the issue.

If heavy bleeding is interfering with your everyday life you shouldn’t ignore it, as your body could be telling you there is something seriously wrong.

When is a period ‘heavy’?

Though the degree of menstrual bleeding differs from woman to woman, a period can be considered ‘heavy’ when the following symptoms occur:

  • At least one sanitary towel or tampon is soaked through each hour
  • A pad and a tampon is used at the same time
  • Waking up in the night to change sanitary product
  • Bleeding for more than a week
  • Large blood clots
  • Normal day-to-day activities are affected

Extreme tiredness may be an underlying medical condition

Heavy menstrual bleeding often causes women to feel tired, which is normal due to the decrease in oestrogen levels which occurs around this point in your cycle. Your energy levels will usually return to normal within a few days as your hormone levels begin to increase again. However, for some women, the fatigue may last longer and be more extreme. Some women may find themselves completely sluggish and unable to properly carry out routine activities, signifying something more severe.

This should be investigated as there could, in fact, be a medical reason as to why you feel so fatigued during your period. You may generally be a person whose periods cause them to feel more tired than others, or you might have an underlying medical issue like anaemia or an underactive thyroid. The important point to make is that you should never ignore extreme menstrual fatigue.

Iron deficiency anaemia

The most common cause of iron deficiency anaemia is menorrhagia since there is often a significant amount of blood loss. The symptoms of iron deficiency anaemia include tiredness, pale skin, shortness of breath and heart palpitations.

A diagnosis can be given after carrying out a full blood test, to determine whether the number of red blood cells is within the normal range. If diagnosed with anaemia, your doctor will normally advise you to take iron supplements and improve your diet to increase the amount of iron-rich foods you intake.

Where heavy periods are the reason for your anaemia, medication is typically prescribed by your GP. There are several treatment options available for menorrhagia and these will vary from patient to patient depending on several factors, including severity, medical history and lifestyle. Where medication is ineffective, surgical treatment may be recommended.

Hypothyroidism

The thyroid is a small butterfly-shaped gland found in the neck, the function of which is to produce hormones to naturally regulate the metabolism of your body.

Some women who experience extreme tiredness may find that they have an underactive thyroid, which means your thyroid is not producing enough hormones. Other common symptoms include weight gain and feelings of depression. Around 15 in 1000 women in the UK will suffer from hypothyroidism.

Your GP can determine if you have a thyroid problem by carrying out a thyroid function test, taking a blood sample to measure hormone levels. If diagnosed, hormone replacement tablets are prescribed and should be taken daily, with blood tests being carried out regularly to monitor hormone levels.
