Before we get into the whole does Phentermine cause depression thing, we should first take a look at the market for weight loss products and try and take a look at it from a bit wider perspective. First of all, we need to understand that there is an almost infinite number of different products that are advertised as weight loss solutions that will end all other solutions. The reason for this is quite simple. Obesity is a very serious medical issue and it is affecting an ever-growing percentage of population. While we will not go into details as to why this is, we still need to be aware of this fact as it is the main reason why there are so many products on the market.
The next thing we need to do is to differentiate between different kinds of weight loss products. First, you have all those natural products that are being advertised for weight loss. The simple fact is that the beneficial effects of those products are not proven by any independent study and that the manufacturers are pretty much free to say whatever they want, due to the fact that natural products are not required to pass any approval processes. On the other hand, you have FDA approved weigh loss medications, such as Phentermine, the drug that is the main star of this blogsite. These medications have been tested and tried thoroughly by the FDA and other national regulatory agencies that make sure the medications that are introduced onto the market are safe and that they are efficient. This puts these medications on top very clearly and makes them solutions for people who want science and facts over hype about natural products and advertising quips.
And this is how we come to the answer to the question from the title of this article. The answer to the question is quite simple. Phentermine will not 
cause depression in the vast majority of cases. In fact, depression is one of the least common side effects possible when taking Phentermine. The simple fact is that the manufacturers of Phentermine are required to list all the side effects that have occurred to at least one person who was using their product, even if it is a single case and even if the side effect cannot be directly connected with the medication. Depression is among the least common side effects and the percentage of people that have experienced depression is literally negligible.
The question now becomes why there is so much talk about Phentermine causing depression. First of all, you need to factor in the fact that depression is difficult to diagnose properly and that many people who are simply feeling down will report depression. This gives enough ammo to the manufacturers of natural products for obesity to come down on Phentermine and to claim how this medication will cause the people to become depressed. They know that their products are much less effective than Phentermine and that fear mongering is their best advertising strategy. It is important to keep this in mind as it explains quite a lot.In conclusion, it is extremely unlikely that Phentermine will cause you to become depressed and the likelihood of this happening is further minimized by the proper use of this medication, when it becomes virtually impossible.
