Hello,

The commonest cause of an enlarged spleen together with dry mouth is anaemia. Since anaemia is most commonly due to deficiency of iron, it is likely that you are also suffering from other deficiencies like Vitamin B (a very common cause of dry mouth) and fluids (another common cause of dry mouth as well as headaches).

If you have ever travelled in the tropics, your enlarged spleen could have been the result of infections like Malaria, Typhoid, Leishmaniasis etc. All these cause an enlarged spleen that remains enlarged even after the symptoms of the disease have died down.

Other causes can be :

- Liver Cirrhosis which causes all the symptoms that you have, like enlarged apleen, dry mouth and headache, as the liver fails to metabolize the nutrients you eat.

- Vitamin A Toxicosis - This can also cause an enlarged spleen and dry mouth but I have not come across anything on headaches.

You can see more about enlarged spleen, the symptoms and the causes here:

The simplest diagnosis is that you are suffering from dehydration which is responsible for the headache and dry mouth. And perhaps the resulting weakness has made you more conscious of your spleen.

Please drink a lot of fluids and juices, especially lemon juice ( a wedge of lemon squeezed in a glass of water with a pinch of salt and a tablespoon of sugar) thrice daily. If you do not feel better in a week, please see a doctor for a thorough check up.

I hope that helps.

Thank you.
