Hello and thank you for your question! Constipation is a real problem for some people and it can be a real concern when it occurs frequently. An old expression says: everytime we succeed in the toilette is a little victory! Getting back to your wife: there could me many reasons for constipation, including medical conditions, lifestyle issues, and personal characteristics. The best way to address constipation is through changes in eating habits and other lifestyle changes. Changing eating habits means to use a lot of fruits and vegetables, avoid processed, salty, fat, spicy foods and red meat, eating small proportions of food and frequently, drinking a lot of water, avoiding alcohol and pastry foods, etc. Lifestyle changed include wheight loss, being physically active, trying to overcome stress, etc. You can also use anti-constipation natural products such as senna leaves tea, but this should not be used for prolonged time as it can irritate the bowels. In summary, I would recommend using of medicaments only to treat acute constipation, otherwise the above changes in eating habits and lifestyle should relieve the constipation on the long run! Hope it helps!
