There's a lot to cover, so first of all, please make an appointment (at least 1 month before your trip) with your GP / practice nurse / travel clinic (I used to work in a travel clinic), where you can get advice about immunisations, malaria risks, general health precautions etc. Some vaccines are available on NHS, but not al; malaria tablets are never provided without charge.
Concentrate on avoiding getting diarrhoea - freshly cooked food is usually best, street food is often fine as it's freshly cooked, not kept hot like hotel buffets; salads are best avoided unless you'er absolutely sure it's been washed in treated water; don't drink tap water, but buy bottled water or take a bottle and iodine or chlorine solution / tablets to treat drinking water and for teeth brushing; Arab tea and coffee tends to be very sweet, with lots of sugar - OK, as long as you account for the sugar content. If you get diarrhoea and / or vomiting, best keep drinking fluids, with oral rehydration solution sachets if needed (can buy Dioralyte, Rehydrat etc in UK pharmacies or buy sugar & salt measuring spoon from TALC [Teaching Aids at Low Cost]). Only take anti-diarrhoea tablets eg imodium if essential eg before a long journey. Oral immunisation against cholera, called Dukoral, gives some protection against other causes of diarrhoea - ask practice nurse / travel clinic.
Remember about other health risks such as sunburn, road accidents etc.
