Is it permissible to use an enema as medical treatment?
Question

                It was reccomended to me to do an enema as a medical treatment for a problem I am having. Is this a permissible treatment or not.
Praise be to Allah.There is nothing wrong with using this 
    treatment, if it is prescribed for you by a competent doctor. 
The scholars (may Allaah have mercy on them) have stated that it is permissible to use an enema 
    as a medical treatment, and some of them did that, such as Abu Yoosuf the companion of Abu Haneefah, and Imam Ahmad (may Allaah have mercy on 
    them). In this case it is permissible to uncover the ‘awrah because there is a need to do so. 
Al-Kaasaani said in Badaa’i’ al-Sanaa’i’ 
    (5/128): 
There is nothing wrong with enemas because 
    that is a kind of medical treatment, and it is something that is recommended because the Prophet  (peace and blessings of Allaah be upon him) 
    said: “Seek medical treatment, O slaves of Allaah, for Allaah does not send down any disease but He also sent down the cure, apart from death and 
    old age.” 
Narrated by Ahmad, 17987; Abu Dawood, 3855; 
    classed as saheeh by al-Albaani in Saheeh Abi Dawood, 3264. 
Al-Sarkhasi said in al-Mabsoot, 
    10/156: 
With regard to looking at the ‘awrah, that is haraam… but if there is a reason for doing so, 
    there is nothing wrong with looking at the ‘awrah for a necessary purpose. That includes: 
When a woman is giving birth, (her 
    attendants) may look at the vagina and other parts of the woman’s body. 
Similarly a man may look at the site where an 
    enema is given, when necessary. 
In the case of sickness, there is a necessary reason, and an enema is a kind of medical 
    treatment. The Prophet  (peace and blessings of Allaah be upon him) said: “Seek medical treatment, O slaves of Allaah, for Allaah does not 
    send down any disease but He also sent down the cure, apart from death and old age.” And it was narrated that Abu Yoosuf suffered from emaciation 
    so it was said to him: An enema will relieve you of the emaciation you are suffering. So there is nothing wrong with showing that area to the 
    person performing the enema. This is correct, because extreme emaciation is a kind of sickness. 
Al-Mirdaawi said in his footnote to 
    al-Furoo’ (2/171): 
Is it makrooh to have an enema, whether that 
    is necessary or not? Then he said: The correct view is that it is not makrooh, rather it is permissible if there is a need, but it is makrooh if 
    there is no need…. Al-Marroodhi said: It was prescribed for Abu ‘Abd-Allaah – i.e., Imam Ahmad – and he did it, i.e., an enema. 
And Allaah knows best.
