### Patient: Doctor, I've been experiencing severe swelling in my legs and have recently been having difficulty breathing while smoking. Can you tell me what's going on? 
### Doctor: It sounds like you may have hyperlipidemia, which is a condition where there are high levels of lipids, or fats, in your blood. This can cause lymphedema, or swelling in the legs, and also lead to problems with the lungs, especially if you're a smoker.
