Sir: Nowadays, chewing gutka (betel nut) has become a fashionable activity. Even children are seen doing it openly. Due to its flavoursome taste, easy availability and low price, it is popular among poor children. Many hospitals are full of patients affected by the negative health consequences of chewing gutka. It is even more hazardous than tobacco. The excessive use of gutka can eventually lead to throat cancer. It can also alter blood sugar levels and raise the risk of developing type-2 diabetes. Apart from these harmful effects, doctors say that it can also cause loss of appetite, unusual sleep patterns and loss of concentration. Besides, gutka users are easily identified by their prominently stained teeth. These stains are difficult to remove by normal brushing and usually need the attention of a dentist. It is unfortunate that despite knowing its harmful effects, people continue to use it. Government should take a stand on this serious issue. Gutka should be banned everywhere so that the precious lives and health of people is not put at risk. SYEDA MAHA QADRI Karachi
