Phentermine Side Effects
In order to understand why Phentermine can cause such various side effects, we need to understand how this medicine works.
Phentermine is a catalyst for production of stress hormone Noradrenaline.
Noradrenaline gives a stunning effect of the suppression of appetite the main purpose why we use Phentermine.
But the effect “Suppressing Appetite” comes from a more global and the scale effect in our body “Fight or Flight” – this is how our body reacts to the world’s dangers, including violation and damage to an environment.
This reaction activates human strength to survive, struggle and escape.
How It Manifest
Reacting to dangers, all human senses are sharpened allowing us seeing even in the dark, making us more sensitive and giving us more energy. We are able to work faster because our body gets more air and this oxygen is carried from the air to our muscles.
We experience reduced blood flow to our skin, kidneys and digestive system which helps to avoid blood loss because of injuries, increase sweat and reduce saliva production. We are becoming less sensitive to pain, because we get more endorphins (hormones that naturally kill pain).
Besides this, human arteries are narrowed and veins are extended. This allows the blood returning to our heart.
And of course, fight-or-flight reaction helps to reduce appetite and lose weight, as a result.
Phentermine interferes with the brain’s work that regulates body’s organs such as blood and heart, skin, hair, teeth, stomach, etc. Thus if it messes up with your brain, it brings changes to all these organs as well.
Everybody who is taking Phentermine experiences its side effects. But their impact on every person is different because it depends on general health, age, dosage, terms of the treatment, etc. It is believed that Phentermine 15 mg causes the least side effects, 30 mg brings average damage and 37.5 mg can lead to the most serious changes.
Phentermine should NOT be taken if you have any of the following conditions:
• Heart disease
• High blood pressure
• Thyroid problems
• Anxiety disorder
• Epilepsy or any other seizure disorder.
• Do not take Phentermine if you are taking monoamine oxidase inhibitors (MAOI) to treat depression.
• Also, if you are pregnant or nursing, talk to your doctor about the potential risks involved with taking Phentermine.
Phentermine and Nervous System
Let’s see how Phentermine can mess up with your nervous system that consists of Sympathetic and Parasympathetic systems.
The Sympathetic system has many responsibilities, such as human survival, food production and general activity of the body. And this system is activated by Phentermine.
Parasympathetic system is opposite to the Sympathetic. It is responsible for digestion, relaxation and sleep.
While Phentermine activates Sympathetic nervous system and mobilizes its strengths, it doesn’t pay attention at what is really important for the body at this particular moment.
This weight loss medicine also affects Beta-1 adrenergic receptors in the smooth muscle causing the uncontrolled release of noradrenaline. This can also lead to unpleasant side effects.
