| Diabetes mellitus | Chronic hyperglycemia from insulin deficiency/resistance | Screen neuropathy, wounds, circulation, glucose stability and medication timing. |
| Hypoglycemia | Abnormally low blood glucose | Sweating, shaking, hunger, confusion can progress to seizure/unconsciousness; treat as urgent per emergency plan. |
| Hyperthyroidism | Excess thyroid-hormone effect | Heat intolerance, tachycardia/tremor and medical stability matter. |
| Hypothyroidism | Low thyroid-hormone effect | Fatigue/cold intolerance may affect comfort; stable treated disease is not automatically contraindicated. |
| Cushing syndrome | Excess cortisol effect | Skin fragility, bruising, osteoporosis, weakness and metabolic issues can affect pressure/safety. |
| Asthma | Chronic inflammatory airway disorder with variable obstruction | Position comfortably; acute severe attack is emergency, not massage treatment. |
| COPD | Persistent airflow limitation, commonly emphysema/chronic bronchitis phenotypes | Pacing, positioning and breathing tolerance matter. |
| Pneumonia | Infection/inflammation of lung tissue | Acute systemic illness usually means postpone and medical management. |
| Acute respiratory infection | Viral/bacterial illness affecting respiratory tract | Transmission/systemic symptoms may require postponement. |
| GERD | Reflux of gastric contents causing symptoms/complications | Positioning after meals may matter; massage does not repair LES dysfunction. |
| Peptic ulcer disease | Ulceration of stomach/duodenal mucosa | Severe abdominal pain, bleeding signs or acute symptoms need medical care; avoid aggressive abdominal work. |
| IBS | Disorder of gut-brain interaction with abdominal pain and bowel changes | Symptoms fluctuate; use consent/comfort and avoid cure claims. |
| IBD | Crohn disease/ulcerative colitis: chronic inflammatory disease | Acute flare, pain, fever, surgery/ostomy and medications alter plan. |
| Gallbladder inflammation/stones | Biliary disease causing upper-right abdominal symptoms | Acute severe symptoms require medical evaluation, not deep abdominal massage. |
| UTI | Infection of urinary tract | Systemic symptoms/fever/flank pain may indicate more serious infection and need medical care. |
| Kidney stones | Urinary calculi causing often severe colicky flank pain | Acute severe pain needs medical evaluation; massage does not mechanically move stones through ureter. |
| Chronic kidney disease | Progressive loss of kidney function | Fluid balance, edema, fatigue, skin, medications and dialysis access may affect massage. |
| Dialysis access | AV fistula/graft or catheter used for dialysis | Protect access site from compression/trauma; follow client medical guidance. |
