According to the Centers for Disease Control and Prevention, there has been a significant increase in the diagnoses of autism. In 2000, one in every 150 children were diagnosed with Autism in the US. More recently, the numbers have increased drastically where one in every 59 children are diagnosed. The search for medical treatments has been ongoing. One promising avenue includes analysis of the gut microbiome. Recent research suggests that changes in normal gut microbiota may be responsible for a large range of diseases. This is specifically of interest for autism research because roughly 30-50% of people with autism have chronic gastrointestinal (GI) problems.
Comments
GI
I don't think you need to provide the shortened version of GI, just because it is not used later in the paragraph. If this is part of a bigger piece than you should leave it.
suggestion
You could elaborate on the treatment itself, because there is a sentence introducing the search for a treatment, but the description in the following sentences talk about research in an area and not a treatment itself.
Suggestion
I would like hearing more about how the gut microbiome is related to autism. This paragraph seems kind of short given the topic.
