I have bags under my eyes, but i get enough sleep. what would be the cause of this?

Allergies: The most likely explanation is edema or swelling under the eyes, associated with environmental allergies which are chronic. You should be seen and examined to further investigate your symptoms.

Eye bags: Many causes. Allergies are a possibility. If so, there may be associated itching. Fat herniation is another possibility but this isn't associated with itching. Each have different treatments. Talk to your doctor.

Herniated fat pads: These are fat pockets. They can be removed easily with surgery. This is genetic in nature, you inherited this.

Fluid or fat!: If the "bags" are present every day (not allergies) and go away after several hours, this is fluid, and eyelid surgery can improve, but not eliminate this tendency. Sleep slightly elevated to decrease this. If fat and loose skin, expert plastic surgery can reposition, remove, and tighten this up beautifully. See an abps-certified plastic surgeon for consultation and advice!
