4 min readNew DelhiMar 14, 2026 04:00 PM In an Instagram video, a nutrition recently led five signs that prove you have “sugar in your body”:
“Pehla sign: Aapko bahut zyada urine aata hai (frequent urination)Sign 2: Aapko bahut zyada pyaas lagti hai (excessive thirst)Sign 3: Aapko bahut zyada bhook lagti hai (constant hunger)Sign 4: Aapko brain fog rehta haiSign 5: Skin tags ya skin discolouration — body ke kisi bhi hisse mein.”

But how medically accurate are these claims? And when should these symptoms actually raise concern? According to Dr Vikram Jeet Singh, Senior Consultant – Internal Medicine at Aakash Healthcare, these symptoms can be meaningful, but only when assessed properly.
When do frequent urination, thirst and hunger become concerning?
“These three symptoms — polydipsia, polyuria and polyphagia are classic signs of high blood sugar,” says Dr Singh. “However, they become concerning when they pers for more than a couple of weeks, especially if accompanied unexplained weight loss or unusual fatigue.”
He explains that persently elevated blood glucose levels force the kidneys to excrete excess sugar in the urine, causing dehydration and increased thirst. Meanwhile, when insulin does not function effectively, cells fail to absorb glucose efficiently — leading to increased hunger.
“At that point,” Dr Singh adds, “a fasting glucose test, HbA1c, or an oral glucose tolerance test should be done to rule out prediabetes or diabetes.”Story continues below this ad

Is brain fog really linked to high sugar levels?
“Brain fog can sometimes occur due to rapid spikes or fluctuations in blood sugar,” Dr Singh explains. “Insulin resance can affect how efficiently the brain receives energy.”
However, he cautions against oversimplification. “Brain fog is not specific to high sugar. It may also stem from poor sleep, stress, hormonal changes, nutritional deficiencies or even certain medications. If cognitive sluggishness is persent, medical evaluation is necessary instead of assuming sugar is the only cause.”

What about skin tags and dark patches?
Skin tags and dark, velvety patches, especially around the neck, armpits or groin, are often linked to insulin resance.
“There is a known medical association between insulin resance and conditions like acanthosis nigricans,” says Dr Singh. “But this link is not absolute. Many people with skin tags may have completely normal sugar levels.”Story continues below this ad
He advises viewing these changes as “possible warning signs rather than diagnostic proof.”
“They should prompt testing, not panic,” he adds.
The danger of self-diagnosis through social media
“It can be misleading to conclude you have high blood sugar based only on symptoms seen in videos,” Dr Singh cautions. “Proper laboratory testing is essential.”
He recommends:

Fasting blood glucose
 HbA1c test
 Oral glucose tolerance test (if needed)

“Home glucose monitors can be helpful for monitoring, but they do not replace professional evaluation. These are early warning signals the body may give. Timely testing allows early lifestyle intervention, which can often prevent progression from prediabetes to diabetes,” he concludes.
