It is definitely true that being on oral medications reduces the amount of insulin you need, but you must find out why you were taken off the oral pills when you came into the hospital – were the doctors concerned about your heart, kidneys, or did they just want to manage your sugars as an inpatient with insulin, which is a very common scenario.  Once you know the answer then you will know if you can go back on the oral medication or not.

Usually if a treatment regimen is working, meaning there are no major hypoglycemias, no weight gain, and good HbA1c,  the practice is to continue with that regimen. However, there is no single right way to treat diabetes. There are often many different ways to control the condition. Perhaps there was something about treatment with Januvia that was making your doctor uncomfortable. You should ask him in order to understand his thought process, and his decision to change your medication. And do keep your doctor informed of your progress.  It’s very important that he know what’s going on.

There are several reasons that could account for the fact that taking
insulin injections can lead to weight gain.

The first reason is that before the person was taking insulin the body
was clearly in an insulin deficient state- meaning that the calories
he or she was eating were being wasted in the urine instead of being
stored in the cells.  Once there’s insulin around, if it’s in the
correct dose, all the nutrients will be stored, which leads to weight
gain.  The insulin is just restoring the normal balance. Just like
with anybody else without diabetes, in order not to gain weight we
have eat less and exercise.

The second reason  is that especially in the case of NPH insulin,
where the peak in insulin action happens without really having much
control over it, many patients will eat more than necessary just to
avoid a hypoglycemia. This weight gain is less drastic with glargine
(Lantus) and it seems that there’s even less weight gain with Detemir
(levemir).

Insulin may intrinsically lead to weight gain beyond what I have
mentioned, but it is not clear by what mechanism this might occur.
If you are having trouble you should consult your physician.

Nighttime hypoglycemia can certainly present like this. It happens much more with the older insulins like NPH, which have a peak in action, as compared to the newer long acting insulins like glargine (Lantus), or detemir (Levemir). Detemir does still have a peak, but not as much as NPH.
One easy way of finding out if you are having nighttime hypoglycemia is to set your alarm for around 3 am and you can check your sugars. The body is particularly sensitive to insulin in the very early morning hours, like 2-3 am. This means that the insulin that is present is more effective at lowering blood sugars. This could be compounded by a peak in insulin action, if you are taking something like NPH.
