It's recommended you see a GP if you think you have an iron deficiency, as they can perform a blood count test to see if the number of red bloods cells you have in your blood is normal.

Patient.info recommends you get an appointment if you have one or more of the symptoms listed above for more than a few weeks.

There are a number of reasons you may be lacking in iron, from taking drugs like ibuprofen or aspirin to stomach ulcers, inflammation in your bowel and piles, the NHS says.

Heavy periods and pregnancy are very common causes of the condition.

Iron deficiency anaemia can be common during pregnancy, with another recent study finding that  are iron deficient by their third trimester.

In very rare cases, iron deficiency anaemia can be a symptom of cancer in the bowel or stomach.

Once the cause of your low iron has been pinpointed, there are a number of ways to combat it.

1. Eat more leafy greens and meat

A good way to boost your iron levels is to eat more foods that are rich in iron.

They include:

• Dark-green leafy vegetables like watercress and curly kale
• Cereals and bread with extra iron in them (fortified)
• Meat
• Dried fruit like apricots, prunes and raisins
• Pulses like beans, peas and lentils

If you're finding it hard to include iron in your diet, your GP may refer you to a specialist dietitian, the NHS notes.

You can also help your body absorb the additional iron in your diet by eating foods high in vitamin C, such as lemons, limes, tomatoes and red peppers, Patient.info says.

2. Drink less tea and coffee

Some foods and drinks may also make it harder for your body to absorb iron, so it could be a good idea to cut down on those.

They include:

• Tea
• Coffee
• Milk and dairy
• Foods with high levels of phytic acid, such as wholegrain cereals, which can stop your body absorbing iron from other foods and tablets

3. Try iron supplements

You can also try topping up your iron through supplements.

Cara told The Sun: "Supplementation is a convenient and effective way to boost levels quickly if someone is suffering from iron deficiency anaemia.

"BlueIron is particularly useful at boosting levels as it is in a liquid form and therefore, more rapidly absorbable by the body as it does not need to break down a solid form like a tablet or capsule.

"The unique formulation ensures that it reaches the intestines for effective absorption - particularly useful if you have digestive conditions that affect the absorption of nutrients.

"It provides your full recommended daily reference intake of iron in just one small 10ml dose, plus is formulated in a way that is very gentle on the gut."

You can also take your iron in tablet form.

Some people have side-effects when taking iron, such as feeling sick, an upset stomach, constipation, or diarrhoea.

You should tell a doctor if side-effects are a problem.
