I believe dropsy is a build up of fluid due to the heart not working properly and I'm assuming this is the case with my mother. I've looked the subject up on the internet but can't find much in relation to the problem in very old people. Can anyone enlighten me?
Heart failure is a very common cause of edema but it's not the only one. It's very common for older adults to have chronic swelling of the legs due to "venous insufficiency." Edema can also be caused by kidney problems, liver problems, and a few other causes.
Do try to find out whether your mother's edema is heart-related versus some other cause.
If it's heart-related: you can learn about heart failure in older adults at HealthinAging.org, which is managed by the American Geriatrics Society

Diuretics are indeed a mainstay of heart failure treatment. But my suggestion to you would be to start by getting your parents' permission to talk to the doctor and ask a few more questions.
What you want to know is how substantial the heart failure is. Generally a person with heart failure gets an echocardiogram, which will show how the valves are functioning, whether the failure is systolic or diastolic, and what the "ejection fraction" is.
You basically want to find out whether the heart failure is mild, moderate, or severe. (Technically it is classed in Stages I to IV.)
You especially want to know if it's giving your parent symptoms, and if it's likely to cause an emergency room visit or hospitalization.
Good luck, I hope this helps.
Your mother may need a diuretic to get rid her of some of the fluid but only a doctor can decide and prescribe this or any other medication.
I hope that your parents have appointed you (or someone) as POA for their health. At 90+ denial is no longer an option.
We'd love to know how this works out. Please update us when you have a chance.

Do you live close to your parents? Are you able to speak with the doctor treating your mother, or go along when she has appointments? Sometimes it is better to go right to the source to try and understand what is going on rather than guessing with too little information.
