Abdominal hysterectomy is the surgical removal of a part or all of the uterus by making an incision in the lower abdomen. After the surgery, the patient normally spends 2 - 5 days in the hospital and takes at least 4 - 6 weeks to get completely better. Some of the major discharge instructions are;
- Drink enough water and eat smaller meals that are rich in proteins and fiber and plenty of fruits and vegetables daily. This helps with the healing process and prevents constipation.
- Avoid swimming or taking a tub bath, but can take showers.
- Dressings over the incision should be removed daily and keep the wound area clean.
- Avoid inserting anything such as tampons into the vagina for 6 weeks after the surgery.
- Avoid all heavy activity including strenuous household activities, weightlifting, and other strenuous exercises. Short walking and light household chores can be done.
- Avoid driving if the patient is taking narcotic pain-relieving medicines. Long trips in vehicles or airplanes are not recommended for 4 weeks after the surgery.

The hemoglobin holoenzyme (active enzyme) is a complex of an iron ion and 4 subunits- 2 hemoglobin alpha and two hemoglobin beta. People with sickle cell disease have mutated beta hemoglobins. The mutation is a single nucleotide exchange, that changes the 6th amino acid of  protein primary struture - a Glutamic acid into Valine. This one alteration changes the tree dimentional structure of hemoglobin beta so, that it forms lond fibres that disrupt the normal circular form of the red blood cells.
