Q:

Dear 100 Hour Board,

Does your weight affect the sound and smell of your flatulence? I know a very heavy family member with louder (and grosser) sounding flatulence than anyone else I know.

A:

Dear you,

The sound of flatulence is caused by the gas vibrating the skin of your posterior. I suppose that a larger person would have a larger stomach, which means they can hold a larger volume of gas. They also have a larger posterior, which is compressed by their larger body weight, which I suppose could lead to higher pressure and louder sounds. I'm not an expert of acoustics, nor am I an expert of flatulence, but that seems like a logical explanation to me.

As for the smell, perhaps they eat more, which could mean that they have more foul smelling compounds as a result of their digestion? Again, just an educated guess. You would need to do an actual experiment to determine for sure, but I don't think that anyone would actually want to conduct such a study, so perhaps it's better we leave it at that.

Peace,

Tipperary

Diabetes often occurs with obesity, and excess (and often very unpleasant, IME) is a side effect of at least one of the drugs used to treat it.
