Bone weakness
It is noteworthy to mention that lactose intolerant patients can also develop weak bones, decreased bone density and joint pains. This is not a direct effect of lactose malabsorption but a consequence of giving up milk in order to avoid lactose intolerance. Avoidance of dairy, that also contains essential minerals and calcium for bone mass development without supplementing these in other forms can take a toll on bones especially in old age and middle age women.
