Underweight refers to the condition in which a person’s weight is below the healthy weight. The healthy weight being that which if divided by the height in square meters yields and index of above eighteen kilograms per meter squared. Having an index of below eighteen point five is considered underweight. Those who tip the scales would feel jealous if somebody complains of being skinny yet the truth is that the two extremes have medical implications and being underweight is associated with medical issues such as osteoporosis, fertility problems, weak immune system and many more health complications.
Being too skinny also has the stressful effect of reducing the self esteem that an individual has because it reduces the elegant body shape full of curves which is the desire of most people crave. Being underweight therefore creates a conscious knowledge of the less appeal that the individual has as compared to other people.
Basically there are two types of thin person; the one who has excellent metabolic reaction and keeps on eating but does not increase their weight and the other who is sickly and does not find it easy to eat normally and therefore remains underweight. Of the two, the former is healthy while latter case is not and is susceptible diseases like pneumonia, heart disorder, and tuberculosis and could even be affected by cancer.
