Cushings, Hypothyroidism , PCOD , can all present like this. However, these medical disorders can be clearly diagnosed by hormone tests, ultrasound, blood tests.
If all necessary tests have been done, and they have come back normal, then theres not much reason to suspect disease conditions.
I have had yearly check ups but no blood test should I go to the doctor and request any and if yes which ones?
You should get tested for -
1.Thyroid profile blood tests
2.Cushings and PCOD hormonal work up.
3.ultrasound of the abdomen and pelvis.
