What are some ways to increase my iron intake?

Doctor's Answers 1

Iron deficiency occurs when the body does not have sufficient mineral iron. This leads to abnormally low levels of haemoglobin. That is because iron is needed to make haemoglobin, a protein in red blood cells that enables them to carry oxygen around the body.

If our body does not have enough haemoglobin, our tissues and muscles will not get enough oxygen and be able to work effectively. This leads to a condition called anaemia. Iron-deficiency anaemia is the most common cause of anaemia worldwide. Common causes of iron deficiency include inadequate iron intake due to poor diet or restrictive diets, inflammatory bowel disease, increased requirements during pregnancy and blood loss through heavy periods or internal bleeding.

Iron deficiency has been linked to restless leg syndrome. The person who suffers from restless leg syndrome has a strong urge to move his legs when he tries to sleep. He has an unpleasant and strange crawling or itchy sensations in the feet and legs. It is usually worse at night, meaning that sufferers may struggle to get much sleep.

The vegetarian diet and iron

Vegetarian diets exclude meat, seafood, and products containing these foods. Although the vegetarian lifestyle could lead to better health status in adults, it may also bear risks for certain nutritional deficiencies. Cross-sectional studies and narrative reviews have shown that the iron status of vegetarians is compromised by the absence of highly bioavailable haem-iron in meatless diets and the inhibiting effect of certain components present in plant foods on non-haem iron bioavailability. Vegetarians are more likely to have lower iron stores compared with non-vegetarians. However, since high iron stores are also a risk factor for certain diseases like type 2 diabetes, it is recommended that not only vegetarians but also non-vegetarians should regularly control their iron status and improve their diet regarding the content and bioavailability of iron by consuming more plants and less meat.

One can usually correct iron deficiency anaemia with iron supplementation. Sometimes additional tests or treatments for iron deficiency anaemia are necessary, especially if the doctor suspects that there could be bleeding in the body. Foods such as meat, eggs, and some green leafy vegetables are high in iron. Because iron is essential during times of rapid growth and development, pregnant women and young children may need even more iron-rich foods in their diet.

The body absorbs two to three times more iron from animal sources than from plants. Some of the best animal sources of iron are lean beef, oysters, chicken, and turkey. Although one absorbs less of the iron in plants, every bite counts, and adding a source of vitamin C to vegetarian sources of iron will enhance absorption. Some of the best plant sources of iron are beans and lentils, tofu, baked potatoes, cashews, dark green leafy vegetables such as spinach, fortified breakfast cereals, whole-grain and enriched bread.

Can perlane fillers be seen on a CT scan?

Perlane fillers can be seen on CT scan as soft tissue at the location where it’s injected, especially if it’s injected as a bolus. Fret not, the radiologist and radiographer would have seen many such cases, so do not expect them to be surprised at the findings. In fact, you can let the doctor know this, so that the radiologist doesn’t mistake it as other structures in his interpretation of the scan.

Why do I always feel faint?

What I notice in my clinical practice is that many of my patients who complain of feeling faint have overbreathing or hyperventilation. We normally breathe automatically but external events or stresses can change our breathing pattern and make us feel short of breath, anxious, or ready to faint. When this happens, it’s called hyperventilation, or overbreathing. We breathe in oxygen and breathe out carbon dioxide. In situations where there is overbreathing, we will lose too much carbon dioxide in the air that we breathe out.
