Hi Debbie,

True allergies are medical issues and not surgical problems. Antihistamine medications, nasal steroid sprays as well as allergy shots are some of the treatment options. 

The most common cause of nose bleeds is irritation and trauma by either nose picking or aggressive nose wiping.  Nose bleeds could also be related to a deviated septum causing turbilent air flow and irritation of the septum.  There are other causes of bleeding as well such as cancer and bleeding disorders. 

Stuffy noses can be caused by engorged mucosal lining due to allergies, enlarged turbinates, deviated septum, polyps, masses or tumors just to name a few issues.

Snoring is caused by vibrations and turbilent air flow.  It may be related to intra-nasal obstruction or due to soft palate or Uvula issues or tongue base issues or even larynx (voice box) problems such as laryngomalacea. 

What I am getting to here is that there are lots of causes of what you are describing from the simple and easy to correct to the complex.  Your husband needs to be seen by a good general ENT and evaluated.  He also needs a "sleep study."  Adults who snore require sleep studies to make sure they do not have sleep apnea.  Snoring is easy to fix but sleep apnea is much more difficult to correct surgically and if the snoring which is a possible sign of sleep apnea is corrected then that can give you a false sign of the correction of sleep apnea which may not be the case.

All adults who snore should get sleep studies followed by medical or surgical treatment and then again followed by another sleep study to judge the effectiveness of the treatment.

Weight loss often does improve snoring and even sleep apnea.

Good luck
