Brief Answer:
risk low if immunity intact
Detailed Answer:
HI, thanks for using healthcare magic
It is understandable to be concerned.
Herpes viral infection can spread to different parts of the gastrointestinal tract such as the
esophagus ,stomach and intestines but this is more common in persons who have an impaired immune system such as your brother.
Age may affect immunity and would be slightly diminished at 75 but normally would still be enough to fight the spread of this infection unless there are other factors also affecting the immune status.
Other factors that can impair the immune system are: (1)
diabetes (2)
steroid medication (3) HIV (4) on going infection (5) cancer
So therefore while it is possible for it to have spread, it only normally occurs if the immune system is impaired. If you have an intact immune system, the chance is very slim.
Your doctors can determine if this is the cause of your symptoms via a
biopsy if they suspect this.
In terms of the herpes one, according to present data, 50 % to 70 % or more adults have this virus, and its prevalence (amt of persons with it) rises with age. It is very common, most persons do not even know that the virus is present, most do not have symptoms.
This means that 5 to 7 out 10 persons have
cold sores or are at risk of breaking out with cold sores.
You may or may not have given your brother the infection, it is highly contagious, very common and he could have gotten it elsewhere and it is showing itself because of his immunity.
If you are concerned re your potential herpes
esophagitis though the risk is low, you can speak to your gastroenterologist, as a doctor he or she would be well aware of how common this infection is and would know if further investigations are necessary.
I hope this helps, feel free to ask any other questions
