Thanks for your question on Healthcare Magic.
I can understand your concern.
In my opinion, we should rule out
1.
Drug resistance tuberculosis
2. Intestinal malapsorption syndrome.
If everything goes fine, tuberculosis patients show weight gain after 1-2 months of treatment.
She has already taken 7 months of treatment and not gaining weight, actually loosing weight.
So possibility of drugs not working on her is high.
This is commonly seen with drug resistance tuberculosis.
In this, TB bacilli are resistant to standard tb drugs. So this kind of tb needs second line drugs.
So better to consult her pulmonologist and discuss about possibility of drug
resistant tuberculosis.
Another possibility is malapsorption syndrome. In this, patient loose ability to absorb nutrients from food. So there will be
nutritional deficiency and
weight loss.
So consult her doctor and discuss about these possibilities.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your daughter. Thanks.
