Question

why is more urine excreted

Answer 1

Diabetes mellitus (often simply called diabetes) is one of the most common causes of polyuria. In this condition, high amounts of glucose (blood sugar) collect in your kidney tubules and cause your urine volume to increase. ... It can also increase if your kidneys can't properly control the fluid passing through them.

Answer 2

In$\textbf{ Summers }$ water consumption is increased and as compared with it excretory amount of urine is less.

Most of the water actually evaporated via sweat in summer.

It keeps our body cool and hence concentrated yellowish urine is excreted.
