Indigestion
If you watch what you eat but still continue to gain weight and experience swelling in your ankles, feet, and legs, this can be related to a heart disease.
Indigestion is a common occurrence and is not a cause for alarm. But a symptom of heart disease includes indigestion.
When coupled with other heart disease symptoms like heartburn, palpitations, shortness of breath, and weakness, it can be something that you need to check with your doctor.f
