I`ve gone through your query and various reports attached by you. I`ll try and answer your query one by one:-

1. From your sleep study reports, it is clear that you are suffering from OSA ie Obstructive Sleep Apnoea.

2. CPAP is the first choice of non invasive ventilation for management of OSA.

3. There is nothing grossly abnormal with your lung function test. There may be minimal restrictive disorder which may be because of chest wall as it seems you are overweight.

4. From your sleep studies, i could gather that you have been put on CPAP with 10 cm of water pressure. If symptoms are persisting, the pressure may be graduslly increased or BiPAP may be tried. Consult your sleep specialist.

5. Weight reduction and CPAP are the first line of treatment for OSA. If this does`nt help, some devicse like mandibular advancement devices or some surgery to remove or tighten the loose soft tissue can be tried. However, there success may be equivocal. Consult your sleep therapist.
Venaflaxine is an antidepressant. It may also help in some weight loss. It is also used for sleep related narcolepsy. Your treating physician will guide you regarding the duration of treatment.
Modafinil is used for excessive day time sleepiness and you should continue it.

6. The parotid and submandibular glands show inflammatory changes which may be due to some viral/bacterial infection you may have had in the recent past. Consult an ENT specialist for it.

7. If your symptoms are occuring during day time , you may try using CPAP during day also.

I hope i`ve been able to answer your queries.

Sleep specialist are in just in routine mood that to continue this medicine which is having some doubts keeping in view the present advancements of lab testings.

Regarding your fresh queries- as mentioned by me earlier, the treatment of OSA remains weight reduction and CPAP. Surgical options are opted for only as a last measure and the results may not be very encouraging. I`ll not be able to throw much light on who and where this kind of work is being done in India as this is a surgical speciality and not my field. However, you may try out reconstructive or oral surgeon in Apollo group of hospitals.

For low DHEAS, you will have to consult an endocrinologist or a sexologist.

I may not be the right person to comment on your ECHO and other reports but they appear to be more or less normal except that there may be some overload on heart as indicated by dilatation of aortic root which could be due to hypertension. You should consult a cardiologist.

Regarding your query on Venlaflaxin, checking for levels of various chemicals is really not indicated as effectiveness can be monitored clinically. Your sleep therapist will advise you about it.

please guide for these clarifications-
Please guide-
Can we say that CPAP is a first level of Ventilator therapy? means that CPAP falls under first degree of treatment of ventilator therapy- CPAP falls under same group of ventilation -breathing from out side.
Answered by Dr. Shashi Dangwal 18 hours later

Your question is not very clear.

CPAP is a type of noninvasive ventilation which is being used in many conditions where artificial ventilation is required. Yes it is breathing frome outside with the help of a machine.It is the treatment of choice in conditions like OSA where simple strategies like weight reduction fail. In many other conditions, in advanced stages, where artificial ventilation becomes mandatory, non invasive ventilation like CPAP is tried instead of invasive ventilation as first choice since it is much safer.

I recently started feeling a fullness in my stomach, accompanied by the feeling of needing to burp (and not always burping) along with some trouble breathing (feeling as if I need to inhale deeply to get full breaths). Also I seem to be yawning alot but my sleeping patterns have not changed (sleep about 7-9 hours a day all through the night). Before this started I have been eating alot of spicy food and thought that information may be important.
