More details

Connecting Damsup to my symptoms

Damsup does not mean that phlegm or water has solidified in the body

Damsup is a Korean medicine term describing a pattern where bloating, nausea, body heaviness, sticky secretions, and a sense of swelling appear together. It is not the same as a finding of fluid accumulation on an imaging test, nor is it used as a single disease name.

Observe if digestion and body heaviness change on the same day

We ask whether head heaviness, phlegm, and swelling worsen when you feel blocked after meals, and whether they improve together when bowel movements and sleep change. The prescription direction is determined based on existing tests, medications, and patterns in daily life, rather than relying solely on the tongue or pulse.

Do not reduce water intake or seek diuretics based on Damsup

Even if it looks like edema, actual weight, indentation when pressed, urine volume, and shortness of breath must be checked. Record whether bloating, nausea, and body heaviness change together on the same day. Since Damsup is not a test result showing fluid accumulation, sudden swelling, dyspnea, or decreased urination should first be evaluated at a medical institution.

Frequently Asked Questions

Frequently asked questions regarding Damsup

If it is Damsup, should I drink less water?

That is not what it means. Arbitrarily reducing water intake can lead to dehydration and constipation. We first examine whether edema is actually present and if there are causes to check, such as the heart, kidneys, or thyroid.

Is it diagnosed as Damsup if there is a lot of phlegm?

A diagnosis is not based on phlegm alone. We determine the Korean medicine pattern by comprehensively checking for nausea, post-meal discomfort, a feeling of heaviness in the body, and changes in bowel movements while evaluating respiratory diseases.
