Detailed Answer:
Hi,Madam.

I have carefully read your query and understand your concern.

Dry mouth/lips more aptly known as xerostomia can be a common symptom in women.

The most common causes in your case could be associated diabetes mellitus or an underlying autoimmune process "sjogrens syndrome' or just an idiopathic(cause unknown )

I recommend you to undergo blood sugar testing and an ANA screen.
following measures can help you to keep your dry mouth/lips away:

1.Chewing sugar free gum.

2.Sugar free lemon drops.

3.Drugs like Pilocarpine(salagen) and Cevimiline(Evoxac)-ceonsult your physician w.r.t these medications.

4.Artificial saliva substitutes and oral lubricants containing glycerine.

5.Use toothpaste containing fluoride and calcium.

6.Use non alcohol based mouth washes ex BIOTENE.

7.Drinking more water especially while eating.

8.Hydrating balms like Vaseline helps.

9.Maintain good oral hygiene

I also advice you to review your drug history with your treating history as few drugs with anticholinergic action can cause such dryness.

You can continue with your current prescribed medications.

I strongly recommended you to get the above tests.
In case they are found to be negative ,above treatment usually suffices.

I hope this info is helpful to you,
