Controlling Your Blood Sugar When You Have Fibromyalgia

fibromyalgia and blood sugar

The complexity of Fibromyalgia pain syndrome causes many other complications. Many fibromyalgia patients are prone to Reactive hypoglycemia, a condition where one’s blood sugar level becomes dangerously low after having a meal.

Fibromyalgia and Insulin Sensitivity

There’s actually a well-established link between insulin sensitivity and fibromyalgia pain syndrome. Researchers are very much aware of the fact that a lot of those who were suffering from fibromyalgia are highly susceptible to reactive hypoglycemia. Furthermore, this can be made worse when patients feel the need to increase their energy by eating more carbohydrates, which in turn, lead to sugar crash.

What is Reactive Hypoglycemia?

Reactive hypoglycemia is not the same with hypoglycemia, which takes place after fasting. Fasting hypoglycemia is a low blood sugar that takes place as a result of not eating anything at all. On the other hand, reactive hypoglycemia is often overlooked because it does not manifest itself in the same way as fasting hypoglycemia. It actually takes place within a few hours after eating a huge amount of carbs.

The quick rush of the carbs getting into our small intestines can lead to the rapid absorption of glucose. This causes our pancreas to produce an extremely huge amount of insulin. Our body tries to compensate for the added insulin due to the flooding of carbohydrates by producing adrenaline. This in turn causes blood sugar levels to plummet, and energy level in the individual reduces resulting in lethargy. The immediate response of the individual is to consume more sugar or carbs to gain energy. This vicious cycle repeats itself.

Signs of Reactive Hypoglycemia

Those who suffer from reactive hypoglycemia are often overweight. Regardless of how hard they try, they just cannot lose all those extra pounds. This is a common problem for those who have fibromyalgia.  Moreover, fibromyalgia patients are likely to suffer from hormone imbalances. The imbalances can extend to issues with the insulin hormone. Therefore, making it difficult for carbohydrates to be effectively processed by the body. Some of the symptoms include fatigue, dizziness, headache, sweating, irritability, depression, etc.

How to Prevent Reactive Hypoglycemia?

When it comes to controlling reactive hypoglycemia, it is crucial to understand that your diet has a major influence on your overall well-being. This means that you should design an eating plan that addresses your blood sugar issues and aids weight loss. It is highly recommended that you adopt a diet rich in lean protein, complex carbohydrates and healthy fats. In addition, you can also ensure that your blood sugar level remains within healthy range by using a blood sugar monitor.
