At any one time one in five people feels unusually tired, according to the Royal College of Psychiatrists
We all feel tired from time to time, but the kind of tiredness and fatigue that leaves you struggling to live a normal life, can be a warning sign, and needs investigating.
Are you tired all the time?
This problem is remarkably common. According to the Royal College of Psychiatrists at any one time one in five people feels unusually tired, and one in 10 have prolonged fatigue.
There are a range of medical conditions that can cause this kind of debilitating exhaustion. We’ve looked at some of the most common, with their symptoms.
Why am I so tired?
Iron deficiency anaemia can make you feel tired because having this condition means that you have fewer red blood cells than you should have. Iron is used to create your red blood cells. These then help to carry oxygen in your blood to organs and body tissue. Not having enough red blood cells means that vital parts of your body don’t get enough oxygen, which leaves you feeling exhausted.
Talk to your GP about having a blood test. If you are anaemic they may suggest taking iron supplements to bring your iron levels back to normal.

Chronic Fatigue Syndrome (CFS)/Myalgic Encephalomyelitis (ME)
The main symptom of this condition is long-term tiredness (fatigue), which is so extreme that its effects are disabling. The fatigue that comes with CFS/ME has a starting point – you may remember when you suddenly started feeling overwhelmingly tired – and feels quite different to other kinds of tiredness. If you’ve had a physically active day, you’re likely to feel even more fatigued on the following day. This can last for a few days before it starts to improve.
Other symptoms can include:
poor and erratic sleep patterns
painful joints and muscles
It’s estimated that about 250,000 people in the UK have chronic fatigue syndrome, but that figure could be higher. The symptoms can start to show quite gradually, but can also come on more suddenly, over just a few days.
CFS/ME can develop at any age, and can wax and wane, lasting from a few months, to decades. The symptoms can go, and you can have long periods feeling better, but it can reappear, and knock you for six again.
The severity of symptoms can vary too. Some people go through periods when CFS/ME fluctuates, so they have good and bad patches. The bad periods can be brought on by high stress levels, high or low temperatures, and illness or surgery.
A smaller group of people with CFS/ME has more severe symptoms that means that they need long-term help and support.
A fairly small section of all of those affected with this condition do regain their health, although this can take quite a long time.
In a few cases, people with CFS/ME can carry on deteriorating, which is unusual in this condition. In these cases it’s important to see an expert, so that other conditions can be ruled out.
According to the ME Association, there is no accepted cure for this condition, and there is no robust evidence for an effective treatment that works for all people with ME.

Type 2 Diabetes is a complex condition, and symptoms include extreme tiredness and fatigue in people with diabetes.
People with diabetes have a high blood sugar level, (either because of a lack of insulin, or from insulin resistance) which is caused when insulin levels are too high for too long. This is because the high blood sugar levels can interfere with how well your body can transfer glucose from your blood to your cells. This then affects the amount of energy you have, and can make you feel extremely tired. Ask your GP to check you for diabetes.
If you are taking drugs for diabetes, you need to monitor your blood sugar levels as these drugs can cause blood sugar levels to drop too low. This is known as hypoglycaemia, and it when it happens it will make you feel very tired. If this happens, you, someone close to you or a doctor need to raise your low blood glucose levels, quickly.
The best foods to help regulate blood sugar
We all have a thyroid gland (it’s positioned in your neck), which produces two hormones that travel around your body in your blood. They are thyroxine (T4) and triiodothyronine (T3), and their job is to make sure that all the cells in our bodies do their jobs and work normally.
However, the thyroid gland can be damaged, by an assault from the immune system, or by the treatment for an overactive thyroid. This can leave you with an underactive thyroid gland – also known as hypothyroidism – which produces too little of the thyroid hormones you need to keep your body running smoothly.
One of the main symptoms of an underactive thyroid is tiredness, but you may also have a slower than normal heart rate, depression, and aching muscles.
In the UK 15 out of every 1,000 women, and 1 in 1,000 men are affected by this condition.
A blood test can check your hormones, and confirm if you have an underactive thyroid gland. Your doctor will be able to prescribe hormone replacement tablets – levothyroxine – which boosts your thyroxine levels, and should make you feel better.
Anxiety, stress and depression
Mental health issues can play havoc with your sleep. If you are feeling stressed or anxious it can be hard to get off to sleep because of the thoughts and worries buzzing about in your head. You can also struggle with disturbed sleep, and wake up throughout the night, or have nightmares, and even start sleep walking.
If you struggle with these sleep problems for some time, they can then be the cause of more anxiety and/or phobias about getting off to sleep. This can make your sleeping problem even worse.
Strategies for beating insomnia
Depression can also lead to sleep disruption, particularly disturbed sleeping patterns, especially sleeping through the day. Oversleeping can bring on insomnia, exacerbating your sleep problems. And if you aren’t sleeping well, or for long enough, this can leave you feeling utterly exhausted, and struggling with daily life.
Talk to your GP about ways to help tackle the underlying problems of anxiety, sleep and depression.
