Patient's question:

Detailed medical condition and consultation purpose: After the full moon, she was found to have abnormal bowel movements, with the longest period being 5 days without a bowel movement. The family would use soap sticks or glycerin suppositories to help her defecate every time she didn't go for 4 days. During the constipation period, she ate little and was irritable.

Doctor's answer:

Hello: Common treatments for constipation include:
(1) Training bowel habits to cultivate a habit of defecating at fixed times each day. When a child is defecating, it is best to avoid external distractions, such as playing with them or reading stories, as this may divert their attention and hinder defecation.
(2) Correcting poor dietary habits, such as picky eating, and increasing the intake of fresh vegetables and fruits.
(3) Shaving soap into small finger-sized pieces, about 3–4 cm long, moistening them with water, and inserting them into the rectum to stimulate defecation.
(4) Using glycerin suppositories for enemas, with a dosage of 5–10 mL per time.
(5) Mixing glycerin with an equal amount of water for enemas, with a glycerin dosage of 5–20 mL per time.
(6) Using 30 grams of white honey, simmering it over low heat until it becomes viscous, then shaping it into pills. If the child’s finger is the size of a small finger, use one pill per time, inserting it into the rectum.
(7) Using 1% soap water or physiological saline for enemas. Children under 3 years old are more suitable for saline. The dosage is 50 mL for those under 6 months, 100–200 mL for those aged 6 months to 3 years, 200–300 mL for those aged 3–7 years, and 300–500 mL for those over 7 years.
(8) Children can take liquid paraffin before bed, with a dosage of 0.5 mL per kilogram of body weight.
(9) Taking 9 grams of Mahuan Runtian pills before bed each night.
(10) Taking 1–2 pills of Niuhuang Shangqing pills before bed each night.
(11) In some cases, a child’s stool is hard and stuck at the anal opening. Adults may need to use their fingers to remove the stool.
