hi,
thanks for the query.

according to your description and photos the possible causes are,

-caput medusae: dilated veins around the umbilicus are called caput medusae,

these can be seen in conditions like, chronic Hepatitis B, chronic Hepatitis C, alcoholic liver disease, portal hypertension, cirrhosis, drug induced etc.

As you told that at present you are not having any problem, chronic causes comes first.

Other causes of dilated abdominal veins are,

-blood vessel disorders like blocking of blood vessels, inflammation etc.
-disorders affecting blood vessels like hypertension.
-Abdominal distension, ascites etc.

Though at present you are not having any symptoms, sometimes this dilated veins can be due to some underlying pathology as I said above, better to visit physician and undergo general checkup which will find out the cause.

Hope I have answered your query. I will be available to answer your follow up queries. If you are satisfied with all my answer, please rate the answer after closing the discussion.
     
take care.

hi XXXXXXX,

there are no sufficient evidences to say that antacids used for acid reflux can cause dilated blood vessels.

fatty liver can be the cause of your dilated veins as it can be because of alcohol ingestion or as it occurs prior to cirrhosis of liver,
in both these conditions caput medusae can be seen.

so you better consult physician once and get examined.

Wish you Good Health, If you are satisfied with my response please rate the answer after closing the discussion.
take care.
