We can't yet fully explain why some people develop severe reactions to insect stings while most don't.
open
Global / Unspecified, Global
Severe allergic reactions to insect stings can be life-threatening, and predicting who is at risk before a first severe reaction occurs remains difficult with current medical knowledge. Better prediction could help prevent dangerous, sometimes fatal reactions.

We don't have an effective way to prevent the chronic joint damage caused by untreated psoriatic arthritis.
open
Global / Unspecified, Global
Psoriatic arthritis can cause lasting joint damage if not treated early and effectively, yet diagnosis is sometimes delayed because symptoms can be mistaken for other conditions. Faster diagnosis and more effective early treatment remain an unmet need.

We haven't solved how to detect and treat postpartum cardiomyopathy early enough to prevent serious complications.
open
Global / Unspecified, Global
This rare but serious heart condition can develop around childbirth and is sometimes missed or diagnosed late because its symptoms can resemble normal postpartum fatigue. Faster, more reliable detection remains an important unmet need.

We can't yet fully prevent the recurrence of bacterial vaginosis in women who experience it chronically.
open
Global / Unspecified, Global
Recurrent bacterial vaginosis affects a meaningful share of women despite standard treatment, suggesting current approaches don't fully address the underlying imbalance causing it. A more effective long-term prevention method remains needed.

We don't have an effective way to prevent the chronic fatigue that sometimes follows major surgery.
open
Global / Unspecified, Global
Some patients experience persistent fatigue for months after major surgery that goes beyond typical recovery time, and the reasons for this aren't fully understood. Better prevention and treatment of post-surgical fatigue remains an underexplored area.

We haven't found an effective, affordable way to treat elephantiasis in all the regions where it remains endemic.
open
Global / Unspecified, Global
This disfiguring and disabling condition continues to affect millions in tropical regions, and while some treatments exist, access remains inconsistent and the underlying infection prevention needs further improvement. Closing this gap remains an ongoing global health priority.

We can't yet fully explain why some people develop chronic complications from otherwise mild cases of COVID-19.
open
Global / Unspecified, Global
A portion of people who had only mild initial COVID-19 symptoms went on to develop long-lasting complications, while many with more severe initial illness recovered fully. Understanding this mismatch remains an important open research question.

We don't have a reliable way to detect early kidney damage caused by high blood pressure before it becomes serious.
open
Global / Unspecified, Global
High blood pressure can silently damage the kidneys over years before any symptoms appear, and by the time damage is detected, it's often already significant. Earlier, more sensitive detection methods remain an unmet need.

We haven't solved how to prevent the recurrence of shingles in people who've already had it once.
open
Global / Unspecified, Global
People who've had shingles once remain at risk of developing it again, and current prevention through vaccination isn't uniformly accessible or effective for every at-risk group. A more comprehensive prevention approach remains needed.

We can't yet fully prevent the digestive issues that sometimes follow long-term antibiotic use.
open
Global / Unspecified, Global
Extended antibiotic use can disrupt gut bacteria in ways that cause lasting digestive problems for some patients, even after the antibiotics are no longer needed. Better protection of the gut microbiome during necessary antibiotic treatment remains undeveloped.

We don't have an effective, scalable way to detect gestational diabetes earlier in pregnancy in low-resource settings.
open
Global / Unspecified, Global
Standard gestational diabetes screening often happens later in pregnancy and can be logistically difficult to access in under-resourced areas, delaying diagnosis and management. Earlier, more accessible screening remains an unmet need.

We haven't found a way to fully explain why some people develop chronic post-surgical pain after routine operations.
open
Global / Unspecified, Global
A subset of patients develop long-lasting pain after surgeries that are usually uncomplicated for most people, and the biological reason for this difference isn't fully understood. Better prediction and prevention could reduce this often overlooked outcome.

We can't yet fully prevent the recurrence of migraines triggered by hormonal changes in some patients.
open
Global / Unspecified, Global
Hormone-related migraines can be particularly difficult to prevent using standard migraine treatments, leaving affected patients with limited effective options. A more targeted prevention approach remains needed.

We don't have an effective way to treat chronic hiccups that persist beyond a few days in rare but serious cases.
open
Global / Unspecified, Global
While uncommon, some patients experience hiccups that persist for weeks or longer, disrupting sleep, eating, and daily life, and effective treatment options remain limited. A more reliable treatment approach for these rare cases remains undeveloped.

We haven't solved how to prevent malnutrition-related anemia in pregnant women in food-insecure regions.
open
Global / Unspecified, Global
Anemia during pregnancy increases risks for both mother and baby, and it remains common in regions where access to iron-rich food and supplements is limited. Closing this nutritional gap remains an unresolved global health priority.

We can't yet fully explain why some patients develop chronic complications from Lyme disease despite early treatment.
open
Global / Unspecified, Global
Even when Lyme disease is caught and treated early, a portion of patients still develop lasting symptoms, and doctors don't fully understand why treatment doesn't fully resolve the illness in every case. Solving this could improve outcomes for a currently underserved group of patients.

We don't have an effective way to prevent the joint pain that sometimes follows chikungunya virus infection.
open
Global / Unspecified, Global
Chikungunya can cause joint pain that persists for months or even years after the initial infection has cleared, and current treatment options for this lingering symptom remain limited. A more effective long-term treatment remains needed.

We haven't found a reliable way to detect thyroid cancer early in populations without routine neck screening.
open
Global / Unspecified, Global
Thyroid cancer is often discovered incidentally rather than through routine screening, meaning some cases are caught later than they could be with more proactive detection. Expanding accessible screening remains an underused opportunity.
