A terrible illness

The first time I heard about this illness was when I was twelve .My uncle was diagnosed with diabetes at the age of thirty. I remember how he suffered in those days. And the suffering was even bigger because he had to restrict what was of big importance to him "The Food”. He was raised with the mentality that people should live to eat and not eat to live. A kind of though that still some people have, especially old people. So when he was asked to go under a diet he just became hysterical.
His doctor warned him to control it or the consequences could be terrible — he could end up blind or lose a leg. His kidneys could fail.
Diabetes affects the sugar level in person’s body and the psychological mental state too. A diet for people with this ill is based on a reduced amount of carbohydrate. And they should avoid any kind a sugar excess.
Unfortunately, that was too much for my poor uncle, he could not control himself as far as food was concerned, he ate everything he could, then he faced the crisis of having his body infected with high sugar level.
Even his personality changed completely. He became a child who went furious whenever his wife or children encouraged him to stop eating and to stat a diet. He became jealous, evil and greed .As controlling his body reaction to sugar was a lost fight sooner he got immersed in a deep, unbearable depression. It affected him in such a way that in a matter of 10 years he lost his job. Having no job made it even worst; just like lost sheep he found refuge in alcohol and gambling. This person was not the one who used to take care of me anymore, he was somebody else .A person who gambled 3 cars, a house, who drank my scholar tuition every month.
He maintained this behaviour for years and years, even after he was kicked off my house, even after he lost eeverything, even after 3 hearts attacks and a close encounter to death. Last year he lost his leg, but all the same he keeps his evil habits against himself.
The last thing I knew was that he was trying to defeat his addiction of alcohol. I whish he could do it. All the same it is too late.
