ICD-11
According to the ICD-11, a BP-II patient will have experienced episodic experiences of one or more hypomaniac episodes and one or more major depressive episodes, and no history of a manic episode or mixed episode. These symptoms cannot be explained by other diagnoses such as

Cyclothymia
ADHD
Oppositional Defiant Disorder
Schizophrenia and other primary psychotic disorders
Substance-Use Disorder
Personality Disorders
Other Mental illness
Physical issues such as a brain tumorThe specifiers are the same as the DSM-5 with the exception of catatonic features and if symptoms have occurred with or without psychosis about 6 weeks after childbirth

Differential diagnoses
The signs and symptoms of BP-II may overlap significantly with those of other conditions. Thus, a comprehensive history, medication review, and laboratory work are key to diagnosing BP-II and differentiating it from other conditions. The differential diagnosis of BP-II is as follows: unipolar major depression, borderline personality disorder, posttraumatic stress disorder, substance use disorders, and attention deficit hyperactivity disorder. : 1653–7  In clinical practice, the difficulty of diagnosing BP-II depends on the accurate detection of hypomania, which is frequently dismissed by patients. Patients can present with increased productivity and energy with the absence of signs of instability or disturbance. As such, there is a risk that BP-II is misdiagnosed as generalized anxiety disorder or unipolar major depression. An accurate evaluation of differential diagnoses are crucial, as they guide treatment and prognostic implications.Major differences between BP-I and BP-II have been identified in their clinical features, comorbidity rates and family histories.
These agents should be used only if bloody diarrhea is not present.Diosmectite, a natural aluminomagnesium silicate clay, is effective in alleviating symptoms of acute diarrhea in children, and also has some effects in chronic functional diarrhea, radiation-induced diarrhea, and chemotherapy-induced diarrhea. Another absorbent agent used for the treatment of mild diarrhea is kaopectate. Racecadotril an antisecretory medication may be used to treat diarrhea in children and  adults. It has better tolerability than loperamide, as it causes less constipation and flatulence. However, it has little benefit in improving acute diarrhea in children.Bile acid sequestrants such as cholestyramine can be effective in chronic diarrhea due to bile acid malabsorption. Therapeutic trials of these drugs are indicated in chronic diarrhea if bile acid malabsorption cannot be diagnosed with a specific test, such as SeHCAT retention. Alternative therapies
Zinc supplementation may benefit children over six months old with diarrhea in areas with high rates of malnourishment or zinc deficiency. This supports the World Health Organization guidelines for zinc, but not in the very young. A Cochrane Review from 2020 concludes that probiotics make little or no difference to people who have diarrhoea lasting 2 days or longer and that there is no proof that they reduce its duration. The probiotic lactobacillus can help prevent antibiotic-associated diarrhea in adults but possibly not children. For those with lactose intolerance, taking digestive enzymes containing lactase when consuming dairy products often improves symptoms.
