Seemingly always tired, lethargic and no get up and go? It may well be that you’re iron deficient – it’s a common complaint after WLS. Why and what to do about it? Read on ….
Why are people who have had bariatric surgery at risk of iron deficiency?
If you have had any kind of bariatric surgery, it is possible that you could become iron deficient. You could have low iron levels for one or both of the following reasons.
You could be eating less iron-rich foods, such as red meat, because you may now find them difficult to tolerate. You may be absorbing less iron from your food. After bariatric surgery your stomach can produce less acid. This acid is needed to break down your food and release the iron it contains.
Following a gastric bypass, such as a Roux-en-Y procedure, there are additional reasons why you may become iron deficient. You may be absorbing less iron from your diet, as your food will no longer be passing through the part of your intestines where iron is absorbed. In addition you may have lost, or be losing, blood at the site of your surgery.
Each type of gastric surgery has a different risk of iron deficiency. Generally speaking gastric bypass procedures are more likely to lead to iron deficiency than gastric bands.50% of people who have had bariatric surgery are iron deficient within one year of the surgery. One study also found that between 20% and 62% of patients were iron deficient 4 to 12 years after surgery, depending on the type of procedure used.
If you are a menstruating women who has had bariatric surgery, the risks for iron deficiency are greater still, and iron deficiency can become a long-term problem. Similarly, if you are a vegetarian, or your weight-loss efforts have left you eating more of a vegetarian diet, you may be more at risk. This is because you could be eating less iron-rich foods.
Following bariatric surgery it is important to treat any iron deficiency that develops. You doctor can prescribe therapies that will help you to make the most of your weight loss and that have been shown to improve quality of life in some patients.
Warning Signs of Iron Deficiency Following Bariatric Surgery
One of the main symptoms of iron deficiency is fatigue, a more extreme version of tiredness. If you are experiencing fatigue, you may feel physically and mentally exhausted and lack energy for a number of days each week, even if you have not been doing any physical activities that are particularly tiring. You may be too exhausted to complete normal daily tasks such as getting dressed or going shopping, and you may often feel too tired to spend time with friends or family.
There are also many other signs that may indicate that you have iron deficiency or iron deficiency anaemia. These include:
Dizziness, irritability and loss of concentration Looking pale Shortness of breath and a racing heart Sore tongue or dry mouth Cold intolerance or cold hands and feet Headache
Iron deficiency is not the only cause of fatigue. For example, bariatric surgery can put you at risk of vitamin B12 deficiency, which can also cause exhaustion. It is therefore important that you talk to your doctor about your fatigue, and any other symptoms or health concerns that you may have, so that they can understand the likely cause of your symptoms. From this information they will also be able to suggest the best treatment options for you.
