For example, humans who suffer from diseases like diabetes or chronic gut inflamation typically have less microbial variety in their guts.

例如，患有糖尿躁症的人，他们的菌种贫乏。

What doesn't function well are gut microbial communities with only a few different types of workers.

而缺乏物种多样性的菌落无法良好地运作。

Finally, vitamin D promotes calcium absorption in the gut, so it increases serum calcium, promoting bone formation and decreasing bone resorption.

最后，维生素D促进在的吸收，因此增加了的水平，促进骨生长并减弱骨吸收。

Additional factors include alcohol consumption, smoking, drugs like glucocorticoids, which decrease calcium absorption from the gut through antagonism of vitamin D, and drugs like heparin and L-thyroxine.

其他影响因素包括酗酒、吸烟、糖皮质激素等药物（其与维生素D的拮抗作用会减少质的吸收）以及肝素L-甲状腺素等药物。
