Thanks for the query.
The symptom of of easy fatiguability (feeling of weakness n tiredness
) can be due to a variety of reasons. The common one's are anemia
problems, heart problems, chest problems n few other diseases. Many of these can be detected by examination by doctor and simple tests. You need to be evaluated by a physician and he will advice tests depending on the examination findings.
Since you were married early and if there are many stresses going on in the family then that also could be the cause of these symptoms.
A general physician should be able to help you.
Hope that answers your query. If there are more queries, i will be happy to answer.
