I have often had patients who have more problems on one side of the body than the other. Many patients over the years I have noticed, keep coming back with one or another problem on one side of their body. Sometimes it can be the left kidney, the left hip, the left shoulder or the left side of abdomen. Then there are others who have similar complaints on the right side.
The human body as we know is a fusion of two bodies into one with interconnections between the two. The body has so many duplications within us starting from our brain. The left side of the brain controls the right side and vice versa. The right side of the heart pumps impure blood and left side pure blood. Often when one side of the organ suffers, the other also can shut down its functiion in sympathy - like our kidneys. I have always wanted to research this topic and find out if our immunity is less on one side, are some people more prone to develop problems on one side of their body and if so is this genetically determined.
Then again why do majority of us sleep on the left, why is the head of the fetus in mother's womb in most instances is engaged on the left side - does this determine on which side they will sleep later in their life - can we compare obstetric records and check with individuals their preferences later in their life.
Girls can have different-sized breasts or nipples and this is considered perfectly normal, but is the breast with less fat, less prone to cancer. Likewise one leg can be natuarally shorter than the other - do these people have more joint problems - no one has answers to such questions. The net is perhaps a good medium to conduct such studies - provided a lot of like minded people join hands through a community. Do you want to join such a bandwagon - write to medindia we can take this forward.
