I Am A 51 Year Old Female, After Turning 51

I am a 51 year old female, after turning 51 in April, I started loosing weight in May I have lost 30 pounds, I am thirsty constantly, have severe dry mouth, urinate due to the excessive fluid intake. Need readers not too bad but last eye dr appt 3 years ago I was 20/20, I thought the need for readers was due to the computer use. I can't go to the doctor until next month due to insurance issues. Other than asthma since child hood, gallbladder removed in 1995, and I have developed acid reflux as a result, and I had a hysterectomy in 2013, and I have muscle loss also. Any help is good help. Thank you for your time, oh been 208 for over 25 years few pounds up and down during holidays, as of today I'm at 176. This change was from May to now.
