What Causes Decreased Sexual Activity And Nausea While On Lisinopril?

My mother is 85 and recently has a decreased appetite, nausea when presented food, feels full after 2-3 bites, and describes a feeling of food causing pressure just under her breasts after she eats. She also describes a need to constantly clear her throat for 30+ minutes after eating. She has lost 7 lbs. in less than 2 weeks. Her normal weight is 140 and she s 5 8 . She is in good health and the only medication she takes is 10 mg. lisinopril daily for blood pressure. She is resistant to see a doctor because she doesn t want to trouble anyone if it s nothing serious.
