Arm Intervention/treatment
Placebo Comparator: Nutrient drink Dietary Supplement: Nutrient drink
80ml fermented milk without L. casei Shirota strain, administered orally once a day for 4 weeks

Experimental: Probiotics Dietary Supplement: Probiotics fermented milk
80ml fermented milk containing min. 30 billion live L. casei Shirota strain, administered orally once a day for 4 weeks

Primary Outcome Measures :
  1. Constipation severity score which measures overall signs and symptoms of constipation using the 'Chinese Constipation Questionnaire' or CCQ (Chan et al, 2005) [ Time Frame: 4 weeks ]

    Constipation severity score is patient self-assessment of 6 signs and symptoms of constipation:

    1. Severity of false alarms
    2. Frequency of less than 3 defecations / week
    3. Severity of sensation of incomplete bowel movement
    4. Severity of lumpy or hard stools
    5. Severity of bloating
    6. Frequency of laxative use

  2. Frequency of bowel movement [ Time Frame: 4 weeks ]

Secondary Outcome Measures :
  1. Stool consistency based on modified Bristol Stool scale [ Time Frame: 4 weeks ]
    Stool consistency is self-assessed by subjects as Type 1,2,3,4 or 5.

  2. Stool output quantity estimations [ Time Frame: 4 weeks ]
    Stool output is estimated by subjects visually based on comparison to size of a standard ping pong ball.
