Hi..
Welcome to HEALTHCARE MAGIC..
As per your query the symptoms of
metallic taste in mouth along with increasing weight can be related to reduced levels of thyroid hormones known as
Hypothyroidism and you need to consult an
Endocrinologist and get evaluated..
Smoking can lead to
dry mouth along with metallic taste but cessation of smoking should improve the symptoms an not exaggerate..
Therefore, the probablity of having underlying
hormonal imbalance of thyroid hormone seems to be the more probable cause..
As of now you can chew flavoured sugar free chewing gums and drink plenty of water as it will help in masking of the foul taste as well as improve the saliva flow..
Once the cause is confirmed causing metallic taste in mouth, treatment can be done accordingly for relief..
As you are gaining weight eat a high fibre and low-carb diet and do moderate workout to reduce weight..
Hope this information helps..
Thanks and regards..
