Here comes personalized medicine based on your genetics, not a drug company's or other third party secret algorithm that always results in a recommendation for statins once you reach a given age. This is good news, but hasn't made its way into our family doctor's office quite yet.
We all have an enzyme system called the CYP450 pathway. One of the most common gene mutations in our society today is related to this pathway, making up to 90% of the most commonly prescribed drugs very difficult for many people to metabolize, including statins, steroids, and others.
Here is one definition of the CYP450 pathway:
A group of enzymes involved in drug metabolism and found in high levels in the liver. These enzymes change many drugs into less toxic forms that are easier for the body to excrete.
The thing is, you reach a state of toxicity MUCH faster if you have a CYP450 gene variation. Toxicity can be completely devastating to the liver and to the body as a whole.
So, no, you should not 'age into' statins, steroids, or other drugs. You can have your genes tested to see if you have this gene variation or others like MTHFR, which means that you may not metabolize substances very quickly. If you have both, as I do, you can get yourself into a tough spot by taking even regular doses of these medications. The drug companies will consider your outcome very rare, despite thousands of people having this issue.
