Nothing in this world is stationary not even the tiniest of all disease causing
organisms. Doctors and scientist experience different new strains of
pathogen often. This is an indication that no disease can be talked off as fully
understood. The same is the case for obesity. Incomplete knowledge about
a body disorder can only result into limited effective drug research and
development to curb the disorder or the disease effectively. This is the reason
even the best weight loss pills do not appear to be working. Scientist have
yet to grasp the neural basis of appetite and how best to suppress it. Appetite
is an inborn survival instinct. Abolishing appetite using a drug can therefore
result in mortality cases and the rate may increase if the chemicals involved
fail to work as predicated by test and trials of different kinds in the laboratory.
This has in the past been known to create mistrust between the conventional
drug consumers and pharmaceutical industries.
