Question

Diabetes is a very serious, chronic disease, for which there is no known cure. Classic symptoms of diabetes that often cause patients to seek treatment include weight loss, polyuria (frequent urination), and polydipsia (increased thirst). Treatment focuses on keeping blood sugar levels within an acceptable range through diet, exercise, and medications including insulin. If not treated properly, diabetes can cause a host of complications. For example, diabetes is the leading cause of kidney failure, and the leading cause of new cases of blindness among adults between the ages of 20 and 74. Improperly treated diabetes can also damage the nervous system (neuropathy), sometimes necessitating amputation of digits or limbs. Percentage of population classified as obese (BMI>30.0) Millions of diabetes cases Year (diagnosed) 1990 6.6 11.6 1992 7.5 12.6 1994 8.1 14.4 1996 8.8 16.8 1998 10.5 18.3 2000 12.0 20.1 2002 13.6 22.1 2004 15.2 23.2 2006 17.0 25.1

Explanation / Answer

Based on above data, it is clear that with the increase in percentage of obese people number of diagnosed cases of diabetes also increases. So the correct option is A.

We can rule out options B and C as follows.

Graph B shows an inverse relationship between obesity and diabetes I.e with increase in obesity diabetes cases decrease and vice versa. This is inconsistent with the above data. So option B is incorrect.

Graph C shows that with decrease in time diabetes cases decrease. But from the above data it is clear that with every year diabetes cases increase. So option C is also incorrect.
