According to recent research, the culprit of this disease is the alteration of body temperature. As you know, our body is maintained at an average of 37 ° C (98.6 degrees Fahrenheit, as the research indicates), and this is because our blood acts as a body coolant, just like water in radiators Of cars. But in fibromyalgia, patients can not maintain their body temperature steadily.
What is fibromyalgia?
When we lose too much heat (hypothermia) or gain too much (hyperthermia), the hypothalamus, the brain nucleus responsible for regulating the temperature of our body, acts and tries to maintain the balance inside the organism. It uses blood, and blood vessels. When it is too cold, the vessels close (vasoconstriction) to protect our major organs from temperature. If it is hot, the vessels open (vasodilatation) to cool our body. In the same way, when we exercise or use our muscles for some task, blood flows between the skin and muscles as a coolant as well.
Blood malfunction, the real cause of fibromyalgia
For this opening or closing of the flow to occur correctly there are communications and valves between the blood vessels, are the arteriovenous shunts, controlled by the hypothalamus to open or close when appropriate, thus maintaining body balance. And finally we have the blood capillaries, the smallest form of the vessels of our body that also helps maintain the temperature, among other functions. It emphasizes its high number in feet and hands.
Previously it was known that in diabetic patients the blood capillaries end up injuring themselves, causing loss of sensitivity, and also alteration of temperature in hands and feet. But fibromyalgia goes further, because what is injured in this disease are the valves between vessels, the arteriovenous shunts, which in turn interfere in the activity of the capillaries and also cause an alteration of the nutrition of muscles and tissues Of the skin, in addition to injuring the body cooling system.
Muscle damage responsible for fibromyalgia
Because of this malfunction lactic acid accumulates in the muscle and deep tissues, thus affecting the muscular system and causing pain, eventually leading to fatigue, both typical symptoms of fibromyalgia.
On the other hand, the somatic nervous system, responsible for the sensibility, is also affected by the malfunction of the arteriovenous shunts and when it is hypersensitized sends signals of pain to the central nervous system, further aggravating the symptoms.
So, as you can see, fibromyalgia has little of psychological illness and much of physical illness. The problem so far is the little knowledge we had about it and how to diagnose it, and even more without knowing the cause. Hopefully with this and the next research on the subject we can arrive at a correct diagnosis and treatment.
